I'm not going to search through 500 posts to see if this was said, but
Here's some more evidence of lineage between whales and aritodactyls:
quote:
A number of cellular specializations can be recognized in the mammalian cereberal cortex using simple cytoarchitectural or chemoarchitectural analysis to define specific neuronal sublcasses... ...comparable patterns of expression can be found in members of the same clade. Whales and closely related artioactyls share patterns of neocortical expression of calbindin and calretinin
In other words, whales and artiodactyls share some cellular specializations in the brain that are not shared with other mammals.
