Biogeographic distribution of species Comparative genomics It is interesting to note that in the midth century, despite the relative sparseness of the fossil record and the fact that comparative genomics as a discipline was over a century in the future, the evidence for common descent was regarded as compelling.

The fossil record and comparative genomics have made a powerful case for common descent irrefutable. Just the genomic evidence alone is compelling.

Conversely, there is no reason if special creation was true for God to deliberately insert the same non-functional genetic element into closely related species in exactly the same place in their respective genomes. John Coffin, a leading expert in virology comments on how the pattern of ancient retroviral infection in genomes confirms common descent: Because the site of integration in the genome, which comprises some three billion base pairs in humans, is essentially random, the presence of an ancient provirus at exactly the same position in different, but related, species cannot occur by chance, but must be a consequence of integration into the DNA of a common ancestor of all the species that contain it.

It evolution of retroviruses follows, therefore, that we can infer what viruses were present millions of years ago by examining the distribution of endogenous proviruses in modern species. At this point, I need to stress that this is only one of the lines of evidence that confirm common descent.

He was attacking a straw man version of evolution, and anyone unfortunate enough to take his strategy to heart and try to take on an informed friend would result in significant embarrassment.

Origin of species [Letter]. The descent of man, and selection in relation to sex. Abel recognised four of the five main lines of evidence for evolution: It is useful to anticipate that the evidence for 'vertical evolution' is usually taken from four major areas: Paleontology - the study of fossil remains of extinct animals and plants, including traces of their existence e.

It attempts to establish the order in which things lived. Morphology and Comparative Anatomy - the study of the comparison of living and dead things for resemblances and differences which might suggest relationships between them and indicate whether one form might have been derived from another.

Embryology - the study of developing creatures before their birth. Comparisons are made between the adult or developing forms of other creatures.

Genetics - the study of how the characteristics of parents are transmitted to their offspring, and how variations in these characteristics can arise.

It is also concerned experimentally with breeding research in which new variables are produced and specialized. Missing however is biogeography, which is alluded to only briefly in a footnote. Furthermore, his definition of the evidence for evolution from genetics is not referring to the evidence for common descent from comparative genetics, but rather to the theoretical mechanism behind evolutionary change.

This conflation of evolution as fact with evolution as theory stems directly from his flawed definition of evolution. Evidence for evolution is sometimes taken from biogeography the study of geographical distribution of plants and animals and taxonomy the science of the classification of organisms.

These, however, are not usually the crucial arguments. When arguments of classification are advanced by evolutionists it requires stressing that it is the evolutionist, and not the fossils, which orders the single celled amoeba, first, and next to it places a multicellular hydra, a three-layered worm, an amphioxus, and then a fish, an amphibian, reptile, lower mammal, lower ape, higher ape, and man.

The order is a synthetic one. It no more proves that one form of life came from another than the arrangement of books on a shelf from simple to complex proves that the books "evolved". Both simple and complex may have been produced simultaneously.

Arguments from the classification assume the very thing which must be proved. As I said earlier, the biogeographical distribution of species is one of the strongest lines of evidence for common descent.

More on this later. Furthermore, his assertion that the classification of organisms is entirely arbitrary is false, and betrays a complete ignorance of the principles behind taxonomy.Mar 21,  · Stephen Jay Gould () wrote many other important books, such as Ontogeny and Phylogeny,Ever Since Darwin,The Panda's Thumb,Hen's Teeth and Horse's Toes,The Flamingo's Smile,Wonderful Life: Comment Report abuse.
