The Invalidity of Morphological Homology
The homology thesis of the evolutionists is based on the logic of building an evolutionary link between all living things with similar morphologies (structures), whereas there are a number of homologous organs shared by different groups that are completely unrelated to each other. Wings are one example. In addition to birds, we find wings on bats, which are mammals, and on insects and even on some dinosaurs, which are extinct reptiles. Not even evolutionists posit an evolutionary relationship or kinship among those four different groups of animals.
Another striking example is the amazing resemblance and the structural similarity observed in the eyes of different creatures. For example, the octopus and man are two extremely different species, between which no evolutionary relationship is likely even to be proposed, yet the eyes of both are very much alike in terms of their structure and function. Not even evolutionists try to account for the similarity of the eyes of the octopus and man by positing a common ancestor
In response, evolutionists say that these organs are not "homologous" (in other words, from a common ancestor), but that they are "analogous" (very similar to each other, although there is no evolutionary connection between them). For example, in their view, the human eye and the octopus eye are analogous organs. However, the question of which category they will put an organ into, homologous or analogous, is answered totally in line with the theory of evolution's preconceptions. And this shows that the evolutionist claim based on resemblances is completely unscientific. The only thing evolutionists do is to try to interpret new discoveries in accordance with a dogmatic evolutionary preconception.
However, the interpretation they put forward is completely invalid. Because organs which they have to consider "analogous" sometimes bear such close resemblance to one another, despite being exceedingly complex structures, that it is totally inconsistent to propose that this similarity was brought about thanks to coincidental mutations. If an octopus eye emerged completely by coincidence, as evolutionists claim, then how is it that vertebrates' eyes can emerge by the very same coincidences? The famous evolutionist Frank Salisbury, who got dizzy from thinking about this question, writes:
According to the theory of evolution, wings emerged independently of each other four times: in insects, flying reptiles, birds, and flying mammals (bats). The fact that wing with very similar structures developed four times-which cannot be explained by the mechanisms of natural selection/mutation-is yet another headache for evolutionary biologists.
One of the most concrete examples of such an obstacle in the path of evolutionary theory can be seen in mammals. According to the accepted view of modern biology, all mammals belong to one of three basic categories: placentals, marsupials and monotremes. Evolutionists consider this distinction to have come about when mammals first appeared, and that each group lived its own evolutionary history totally independent of the other. But it is interesting that there are "pairs" in placentals and marsupials which are nearly the same. Placental wolves, cats, squirrels, anteaters, moles and mice all have their marsupial counterparts with closely similar morphologies.283
In other words, according to the theory of evolution, mutations completely independent of each other must have produced these creatures "by chance" twice! This reality is a question that will give evolutionists problems even worse than dizzy spells.
One of the interesting similarities between placental and marsupial mammals is that between the North American wolf and the Tasmanian wolf. The former belongs to the placental class, the latter to the marsupials. Evolutionary biologists believe that these two different species have completely separate evolutionary histories.284 (Since the continent of Australia and the islands around it split off from Gondwanaland (the supercontinent that is supposed to be the originator of Africa, Antarctica, Australia, and South America) the link between placental and marsupial mammals is considered to have been broken, and at that time there were no wolves). But the interesting thing is that the skeletal structure of the Tasmanian wolf is nearly identical to that of the North American wolf. Their skulls in particular, as shown on the next page, bear an extraordinary degree of resemblance to each other.
Extraordinary resemblances and similar organs like these, which evolutionary biologists cannot accept as examples of "homology," show that homology does not constitute any evidence for the thesis of evolution from a common ancestor. What is even more interesting is that the exact opposite situation is to be observed in other living things. In other words, there are living things, some of whose organs have completely different structures, even though they are considered to be close relatives by evolutionists. For example, most crustaceans have eye structures of the "refracting lens" type. In only two species of crustacean-the lobster and the shrimp-is the completely different "reflecting" type of eye seen. (See the chapter on Irreducible Complexity.)
