Anyone examining the different living species on Earth will observe that there are certain similar organs and characteristics among species. This phenomenon has attracted the notice of biologists ever since the 18th century, but the first to link it to the theory of evolution was Darwin, who maintained that there was an evolutionary link between living things with similar (i.e. homologous) organs, and that such organs were a legacy from their common ancestor.
Accordingly, since pigeons and eagles have wings, that means that pigeons, eagles and other such winged birds all evolved from a common forebear.
Homology is a superficial hypothesis put forward solely on the basis of external appearances. The hypothesis has not been confirmed by any concrete finding since Darwin’s time. In particular, no trace has ever been found of the imaginary common ancestors of life forms with homologous structures as proposed by evolutionists. And there are additional hurdles:
The existence of homologous organs in life forms belonging to totally different classes, among which evolutionists also cannot establish any evolutionary link
TWO UNRELATED MAMMALS WITH GIANT TEETH
The existence of extraordinarily similar species, one a placental and the other a pouched mammal, deals a severe blow to the claim of homology. For example, Smilodon (right) and Thylacosmilus (left) both have very large front teeth. The fact that the skull and tooth structures of these two life forms, between which no evolutionary relationship can be established, are exceedingly similar refutes the claim of homology—that similar structures represent evidence for evolution.
The fact that the stages of the embryological development of these organs all show that homology represents no basis for evolution.
Among the examples of species between which evolutionists cannot establish any evolutionary link but which possess homologous structures are those with wings. The bat—a mammal—has wings, and so do birds, and there were once species of dinosaurs that also had wings. However, not even evolutionists can construct any evolutionary relationship among these three different classes.
Another striking example in this context is the astonishing similarity and structural resemblance between the eyes of different living things. For example, the octopus and man are two very different life forms—mollusk and mammal—between which no evolutionary link can be construed. In terms of their structure and function, however, their eyes are actually very similar. Not even evolutionists will claim that human beings and octopi had a common ancestor with a similar eye. These and countless other similar examples make it clear that there is no scientific basis to the evolutionist claim that homologous organs prove that living things are descended from a common evolutionary ancestor. In fact, these organs represent a major impasse for them.
