As strange as it may seem, it was through my works on fish ( I am, in fact, since 1968, date
of my first publication in Zoology, a specialist in Fish Research ) that I came to reconsider the evolutionary history
of all Vertebrates, and finally to assign to man ( Homo ) a position, which may be surprising
at first glance, as an ancestral vertebrate. That is to say that all the other vertebrates, known to this day, have
derived from the human ( or pre-human ) form and morphology.
Classical zoology, indeed, accepts the following order of appearance among Vertebrates : first
came the fish, then the amphibians ( frogs and newts ), then the reptiles ( they are lizards and snakes,
and also - according to current beliefs- the big saurians now extinct ), the birds, and ’above all them’, the mammals,
with man ’at the end of the line’...
This old traditional cliché has been carried on for more than two centuries : in fact, such
an order dated back to the classification proposed in 1758 by Swedish naturalist Carl von LINNE. It was simply
forgotten, at the time when DARWIN’s ideas triumped, roughly one century after, that Linné in his time arranged the Animals
according to criteria of increasing complexification [ hence this series going from fish to mammal ]
simply for own need in classifying animals in a book... In fact, Linné didn’t give a slightest thought to any notion of succession
or evolution of the groups. He didn’t believe that amphibians and reptiles once developed from fish, or that mammals
evolved from reptiles !
A zoologist, like Ernst HAECKEL, who was a fervent admirer of Darwin and often more enthusisastic than
his master, merely took again the old Linnean classification which, as we remember, was a ’static’ one, and he
claimed that these forms of living beings that were already catalogued, were in this order due to be links of
descent, in relation to each other. In this way, the fish surely gave birth to the amphibians, and so on...
HAECKEL, in his well-known phylogenetic trees,
introduced also names of hypothetical animals in the intersections between different groups, called for instance :
’mother-form of the reptiles’ at the junction between amphibians and reptiles. Haeckel thought, it was up to the palaeontologists,
now, to find their bones one day in some sedimentary strata...
This has been the ’frozen’ state in which our Zoology manuals have stayed for more than a century,
with a ’natural’ classification that was quite arbitrary, as afar as the vertebrates and other phyla were concerned.
This has done much to ’falsify’ all the facts dealing with problems of evolution, mainly all facts concerning the
emergence of humans.
And yet, certain researchers, zoologists or anatomists, intended to disturb, going against the
mainstream dogma, and to propose phylogenetical models where they especially insisted on the fact that man,
as a result of his archaic anatomical structure [ we’ll come back to this point in details ], could not be
considered as resulting from a ’recent’ evolution within the mammals - or even the vertebrates in general -, but
represented an ancient [ bipedal ] type, which appeared first at the dawn of the geological ages...
This assumption fits in with the teaching of what may be called ’Tradition’. In fact, the story
of ’’man descending from apes’’ is a completely new scientific invention, which has been dictaded largely for materialistic
reasons, and is based on erroneous extrapolations from fossils that were discovered during the XIXth Century.
We are going to make clear all the way throughout this lecture, that in fact the today ’simian’ interpretation of our origins is
not based on real biological facts. On the contrary, everything shows us [ and the more recent research in Physiology
and Genetics proves this even better, day after day ] that the emergence of man is surely prior to that of current
apes, and also of other living or fossil primates, of all quadrupedal mammals, and even of the vertebrate line, in general.
Earlier I spoke about naturalists who tried to deny the fact that man had a simian ascendency.
I ususally quote 4 names in principal : Pr. Max WESTENHÖFER, German anatomist and
main instigator of the Initial Bipedalism Theory since ; Pr. Klaas de SNOO,
Dutch obstetrician ; Dr. Serge FRECHKOP, Belgian mammalogist of Russian origin ;
and the French/Belgian Dr. Bernard HEUVELMANS, still active [ 1990 ] in a scientific field,
and well-known by the general public, since the publication of a big series of books about very rare, or hidden animals
unknown to science.
I would express here my gratitude to Bernard Heuvelmans and thank him for having initiated
me in the theory of Initial Bipedalism.
Finally, I could also quote many other eminent searchers from the beginning of the XXth
Century, whose ideas on man’s origin did not correspond to the mainstream science : paleontologists,
like Albert Gaudry, Henry Osborn or Edgar Dacqué ; biologists, like Kollmann or Bolk,
and naturalists, like Eugen Kolisko or Hermann Poppelbaum, who belonged to the Anthroposophical School
of the Austrian philosopher Rudolf Steiner.
The evolutionary history of man, as told today by the learned people in University, is but a gigantic farce,
based on erroneous observations and old prejudices which are hard to kill off. There has been, for instance, a lot of talk in the
mediae recently about certain anthropological events, such as the discovery of the female Australopithecus called ’Lucy’,
who is about 3 million years old. She has been presented as the ’Mother of Humanity’... It is all very well,
especially when general public is concerned, to arrange chosen fossils of primates in the desired order, and to witness
their gradual straightening up [ as we can see in certain drawings... ], as well as the development
of the size of skull and encephalon. Paleoanthropologists fail to add that some fossils, duly dated, don’t correspond
to their thesis... In that way, American Donald JOHANSON discovered in East Africa a hominian fossil, named very
prosaically OH 62, that is approximately 1.8 million years old [ a lot younger than ’Lucy’ ]
whose special feature is the possession of very long arms, much longer than those of ’Lucy’ [ who was of similar
stature ]. This is not the best way to develop into modern man... On the contrary, this discovery confirms what I hold to
be true ( in accordance with Dr. Heuvelmans whom I quoted above ), namely that the Australopithecines
are in reality forms which once developed from the genus Homo : they have kept, as the fossils show,
a ’relic’ bipedalism, indeed, and have evolved ( as proved by the lengthening of the arms ) several times
during the last geologic periods ( Plio-Pleistocene ) towards the stage of anthropomorphic apes,
especially when these hominans have left the savannah to go and to live in forests, where they completely mastered the
art of tree-climbing !
The classical theories concerning the evolution of the Vertebrates also ’get round’ the problem
of the emergence from the water of first land vertebrates, by admitting that this event was done by a
curious ’fish with growing legs’, related to today Coelacanths. In the Primary Era, this fish was allegedly
capable of setting about the impossible task of mastering the difficulties of a life on dry land. The question I would like to
ask is : ’’Did such a fish really want to leave the water ?’’. We will come back to this point later.
For the moment, let us stick to the subject of man. There are, currently, 3 scientific theories
more or less which try to explain man’s emergence on this planet. I’d like to add a fourth theory, too :
The first well-known theory is called the African Savannah Theory. According to it, apes are
supposed to have left the forest, about 17 million years ago, somewhere in West Africa, as a result of a change in
climate and tectonic upheavals in this region, and then they went into the savannah. These apes consequently developed
straight body, as many books explain... I quote : ’’in order to see better over the high grass in the savannah !’’.
It is this theory that is still kept in big esteem by anthropologists today. Only some scientists are brave enough to express
a certain doubt : even the least talented would admit that the whole story doesn’t stand up to close examination,
not more than those famous apes who supposedly have learnt to stand on 2 feet...
The second theory which is less known by general public is the Foetalisation Theory,
developed by Dutch biologist L. BOLK, and recently re-examined and presented by scientists like
Desmond MORRIS ( author of ’’The Nacked Ape’’) or Stephen J. GOULD ( author
of a big number of popular-scientific treatises ). According to this theory, man would be an ape’s ftus which had
become sexually mature... The theory explains human appearance by a phenomenon known as neoteny :
this means that an animal conserves throughout its entire existence the features that characterize its ’larv’ or ftus during
early development. A well-known example in Animal world is of certain newts that keep external gills during all their lifes ;
in this way they are able to reproduce in water without ever coming up onto land. Obviously, the facial characteristics
of an adult chimpanzee don’t have a lot in common with a human face, whereas when the animal is young, the outline
of his skull is still harmoniously curved and the facial features do not stick out, as they do in the adult. The ’canine’ aspect
of the shape of the adult’s head appears very progressively, after the milk teeth have been replaced by the definitive teeth.
Certain searchers have used this statement to explain that man was but an offspring of the Great Apes because he retained
many youthful features in his anatomy [ and by the way, there was no need for a fossil to provide the ’missing link’,
because the latter was in fact a ftus ! ]. Apart from this roundness of the skull form, scientists also
noted typical human characteristics in apes’ embryos, such as the fact that the teeth are set vertically in the gums,
the genital female organs are more towards the front than later on ( we can also observe the presence of a hymen
and of outer lips ), the central position of the foramen magnum ( which is the place where the spinal
column enters the skull ), as well as the relative nudity of the body. Nevertheless, rather than considering man as
an ’ape’s ftus which has grown up’, a fact not very plausible from a zoological point of view, I think we should maintain
here that it is the humain being himself who remained at this stage of development. It is the ape which has reached
a ’more advanced stage’ in morphology, by continuing the anatomical and genetical development beyond the point
where human development ceased ! Here is the fundamental difference between the neotenic
explanation ( Foetalisation Theory ) and the Initial Bipedalism Theory.
The third theory regarding man’s origins that I’m going to evoke is the theory of the ’’Aquatic Ape’’,
which was suggested by British biologist Alister HARDY. In France, this theory is known to general public by the
diver Jacques MAYOL, who told about it in his famous book ’Homo Delphinus’ that inspired the
film ’Le Grand Bleu’. Alister HARDY offered the idea that we may have descended from a sea-ape, which belonged
between the quadrupedal Ramapithecus [ existing around 10 millions years ago ] and the more
recent bipedal Australopithecus. This would account for our naked skin [ it would be more precise to say :
with our ’not so hairy’ skin ! ], our large flat hands with traces of the times when they were palmed, the lay
of fat beneath the skin that characterizes our species among all the other primates, as well as the permanent feature
of our bipedalism. Indeed, there is a lot of things that are true in this theory, but I think that the aquatic stage through which
modern man’s ancestors really went through was very more ancient, and cannot be dated from only a few million years.
As far as Initial Bipedalism Theory is concerned, it is not a question of a ’return’ to the aquatic element, but it was
rather the very ’emergence’ from the sea-water of the creature which once engendered the human form. We will later come
back to this point.
In the three theories we have just evoked, as you may have noticed, the
ape [ or another simian form ] is considered as man’s direct ascendant. On the contrary,
the Initial Bipedalism Theory moves away from the common denominator of other theories by claiming that it’s the
ape which descends from man... Moreover man is implicetely recognized [ by his anatomical and morphological
structures ] as the more archaistic of all current mammals ! As the title of this lecture indicated, man is truly the
ancestral vertebrate, i.e. he remained from a morphological point of view closer to the original type of the first
vertebrate that once came out of the water, and was in fact a bipedal mammal, with round skull and big brain !
Our demonstration is based on scientifical facts, as we can find in Embryology and Comparative Anatomy.
Paleontology, as an incomplete science, will not provide us with the direct proof of man’s past existence during the great geological
eras preceding Quaternary, but it will, however, bring us some interesting clues concerning the evolution of the main groups
Let us first deal with the embryological facts. Embryology is the science which studies the development
of organisms from the fertilized egg up to hatching or to birth. Another term, ontogenesis, gives an account
on the individual development from the conception until the adult age. What we call phylogenesis is the science that
deals with the evolutionary history of the whole species. The study of the developement of animals in eggs or in utero
shows that certain embryonic or ftal forms would seem to reproduce ancient stages of the phylogenetical evolution
of these animals : in other words, the ’past’ of a particular species. This is why it is often told that ontogenesis
This is the famous fundamental biogenetic law stated in 1866 by German zoologist
Ernst HAECKEL. It has been used, in accordance with DARWIN’s views, to claim that man, during his embryonic stages,
passes through a ’fish’ stage [ because of the branchial slits which in fact exist in the embryo ], then through
a ’reptile’ stage, through an ’inferior mammal’ stage, then a ’ape’ stage [ because of the soft wooly hair that is
called : lanugo], before becoming finally human...
What is the real state of affairs ? The branchial slits can, indeed, be explained by
an aquatic stage preceding the completion of the human form... but such an aquatic stage has nothing to do with
a ’fish’ stage ! We shall come back later to this point. As far as the ftal hair is concerned, we can talk of a
downy layer of hair which sometimes lingers on the skin of newborn babies after birth, producing ’hairy babies’ [ in adults,
we speak of hypertrichosis ]. But this has nothing to do with animal hairs : it’s entirely
human hair. In reality, and it is very visible in the newborn apes ( chimpanzees or gorillas ), the specific
hairs of the animal grow onto the first layer of human-type hairs. We are aware of an evolutionary new hair-coat : this
clearly proves that apes have evolved beyond humans.
Embryonic stages of Man, Dog ( above )
Bird and Tortoise ( below )
[ after HAECKEL 1868 ]
Let us look carefully at the stages of development of diverse vertebrate embryos which are
comparable [ s. above ], first we have a human embryo ( 4 and 8 weeks old ) and the
embryo of a dog. What is most surprising is that we hardly can differentiate them from one another, except for the tail,
which is longer in the 6 weeks old dog embryo. The other illustration shows us, in a similar way, a chicken embryo
and a tortoise embryo. Here, starting from a stage [ 8 days for chicken, 6 weeks for tortoise ]
a few differences can be observed, which correspond to the general development in their own lineages : notably, the
development of the tortoise shell. But the bird hasn’t yet developed its wings. These drawings put our attention
to the fact [ that is without doubt the more important ] in this comparison of series of embryos :
namely, the astouning similiarity of those, and especially the fact that they all have kept an ’extra-large head’. The early
skull outlines are round and voluminous, even in the tortoise which is a reptile... The human embryo will conserve this
characteristic up to the adult stage, and then clearly appears as the one who has remained closest to the original type from
which they all have developed !
Moreover, it is remarkable that the representation of quadrupedal animals, like the dog in the picture
above, in a vertical position [ i.e., ’standing’ ], seems perfectly natural to us : that would even
not be the case if we imagine it ’lying’, i.e. in the normal position of the future quadruped the dog would in fact be going to
become... As professor Max WESTENHÖFER [ a main investigator of the Initial Bipedalism Theory ]
already wrote in the 1930’s, this phenomenon of an upright position in embryos is directly linked to the level of their eyes,
and to the direction they are naturally facing : in harmony with the globular shape of their skulls.
Man preserves this disposition all his life, whereas animals gradually modify the original inclination,
when they lift up their heads in order to position their vision in front of them : in this way, their eyes
are on the same level as the ( horizontal ) body axis ! Actually, if they would keep eyes lin early embryo
position, when becoming quadrupeds, their eyes would be now facing the ground !
This is why, in the course of development in utero, the animal has to throw back its skull
structure in order to see ahead... Such a development is balanced by the lengthening of jaws that serve as
a ’counterweight’ : this is the formation of the animal snout, and at the same time it necessitates a relative
compression of the brain in a skull-box that is deformed to a more oblong shape.
Coming back now to the round configuration of the embryo head, we can observe in the diverse
quadrupeds that the process of development of skull and brain always goes across a stage which corresponds to the stage
we find in man. In animals, it is altered... The forced changes in position of the eyes automatically govern
a new head carriage, which in turn decides on the necessary modifications concerning the insertion of the spinal column into the
skull. Thus, the foramen magnum get displaced backwards !
In the embryos of all mammals, we observe what we call an original bending of the skull
base, i.e. the osseous surface on which brain lies.
The curved form of the skull base, which is conserved almost unchanged in adult
man [ angle of 120° ], is actually the more primitive disposition. The human anatomy maintains
an archaic feature throughout the course of ontogeny. In animals, we get a more and more horizontal skull
base [ 140° in apes, up to 180°, wide angle, in full quadrupedal mammals ]. So we can emphasize that
quadrupedalism is a derived grade of locomotion in mammals. In this way, equipped with a flat skull base,
animals can see whithout problem when they move.
Bending of the skull base
[ after BOLK, 1926 ]
above : in all mammal embryos
left : adult man
right : dog’s horizontal deck
In bipedal man, the volume and the ’weight’ of the brain ’lock’ the spinal column in an
anatomical disposition, that was the original embryo disposition, too. By the way, the foramen magnum remains in
a low position under the cranium. This allows us to maintain an upright posture when walking. There are evident links
between the volume of brain, the position of head and our bipedal gait...
The globular form of the embryo brain determines the curve of the spinal tube that subsequently
leads to the natural angle of the skull base in humans !
We already spoke of the consequence of such an anatomical feature regarding erect posture. This
disposition is therefore original in mammals [ and in other vertebrates ], since their skulls are invariably
rounder in the embryos than in the adults. Then, bipedal posture must be the more ancient feature.
A derived position during ontogeny brings the spinal column into a horizontal
plane [ parallel to earth ] and causes the lengthening of the jaws : the animal brain is now trapped
and compressed between a stretched back skull and a protruding face...
In this way, animals go during ontogenesis through an early stage that would allow them to
attain the stage of a biped and a considerable dévelopment of cerebral capacities. But they don’t... With opting for
quadrupedalism, they relinquish the capableness of real psychic emancipation !
An objective study of human morphogenesis indeed, contrary to what happens at our times,
should logically start up from the very beginning of the evolutive phase when the first aquatic vertebrates developed. It is
at this moment, as we will see it later on, and at this moment only, that a structural characteristic like the
original roundness of the skull was able to take shape, in the water, at the top of an erect spinal column...
and this development was due purely to mechanical reasons ! We’ll soon come back to this point.
Let us now talk a little about Comparative Anatomy. In the outline of our today lecture,
we shall restrict ourselves with a study of the limbs, but we could also make investigations on the entire skeleton,
as well on the inner organs. It would lead us to believe that bipedal man, indeed, represents the original prototype
of the vertebrates...
The human hand is an extremity which is normally used for touching and grasping objects, whereas in
other mammals, the hand is also [ or exclusively ] used to support the body weight and to provide
a means of locomotion.
Apes have kept hands which are anatomically very similar to man’s, but they often employ them in
quadrupedal gait ( knuckle-walking ). Many herbivores only walk on their fingers
( on one finger in the case of horse ) after the formation of a hoof that developed out of the nails.
We can affirm that the human hand has remained the more primitive, and we can state that it has
never been used for locomotion. Just as the upright body position was acquired at the very moment of the
emergence from water of the pre-hominids, the archaic shape of the human hand developed from the homonculus’
natatory palette [ a very ancient feature in the phylogenesis of the vertebrates, identical to the derived forms
of the fish or cetacean flipper ].
Consequently, the human hand shape has served as a ’starting point’ for numerous
evolutive transformations, like the hoof of herbivores, for instance. The whole arm can also transform into either
a wing [ birds, bats ] or into a pectoral fin, like in the case of fish, cetaceans or sea-reptiles.
The human foot, used exclusively to provide a means of locomotion [ the whole of which,
as a plantigrade foot, is in contact with the ground ], also comes directly from the lower natatory paddle
of the marine animalcule that is the ancestor of all vertebrates. This explains the foot form in the human embryo
at the age of 30 days. About 2 weeks later, the foot has the aspect of a hand : the middle
toe is the longest, and the future big toe is short... Actually, this feature has nothing to do with the ’posterior hand’ of an ape,
as sometimes claimed ! We also observe that the foot is palmed : it’s the same kind of foot which
characterized the archaic pre-hominid before leaving the ocean, about 600 million years ago !
Adaptation to walking on ground consequently modulated the foot architecture : a big toe as we know it, and the sole,
formed by the angles that are made by the tarsal, metatarsal bones and those of the phalanges.
Foot of Macaque ( left )
and Man ( right )
in similar states of development
[after SCHULTZ, 1957 ]
When walking, and especially running, the body weight of man is firstly lying
on his big toe : this staggering development of the first toe is one of the particularities of the human foot. This is obviously
connected with early bipedal gait. On the contrary, the evolution of the foot in tree-dwelling primates is orientated towards
a prehensile structure, where the big toe becomes opposable to the other toes... which inevitably causes
its reduction in size, and even, in long term, provokes its complete disappearing... Actually, the evolution of man’s foot
never passed throughout a stage similar to that of tree-dwelling apes or monkeys ! Man’s natural aptitude
must have been a flat-footed bipedal walking, since the very beginning of the human lineage...
