DNA causes a whale of a problem for evolutionists.
|The 14 species of rare beaked whales (genus Mesoplodon) sport a wild variety of tusks--some jutting straight up, others curving like scimitar blades from the males' jaws. Scientists have long puzzled over the remarkable diversity. Now an analysis of the whales' DNA suggests that it's all about sex. When conservation geneticist C. Scott Baker of Oregon State University, Newport, and colleagues drew up the first molecular phylogenetic tree for Mesoplodon, they were surprised to find that species with similarly shaped tusks are not closely related, as had been thought. Nor do closely related species have similar tusks. The pattern is typical of diversification driven by sexual selection, they report in this month's Systematic Biology. 1|
Here is a typical puzzle for the evolutionists. Biologists have organized living things based on physical appearance and common characteristics ever since Linnaeus. Linnaeus did this simply to facilitate study. He did not believe in evolution.
Evolutionists, however, erroneously think that common characteristics are the result of descent from a common ancestor. The creatures that look most like each other should be most closely related to that common ancestor. Therefore, their DNA should be the most similar. But, the more they study DNA, the more they find that isn’t true.
Ten years ago we first started to document the difficulty DNA analysis was causing for evolutionists. 2 It isn’t getting any better.
How do they explain the beaked whale problem? Sexual selection. But why don’t all female whales find certain tusks sexier than other tusks? Why should tusk shape lead to more diversity? Why is physical appearance of the tusk more important than the tusk’s lethality? In other words, isn’t an ugly sharp sword more important for survival than a beautiful dull one?
The fact is that the evolutionary explanation is inconsistent with the data, so they have to make up fanciful stories to try to explain it.
