>And how is homology determined
Lots of ways. Like if two structures develop from the same groups of cells during development
>Consisting of what, in your view
The existence of endosymbionts and the fact everything uses the same genetic bases
>In that case this is simply a semantic question of labeling rather than a question of any actual objective biological facts
Arguing whether or not something is a leg based on function is semantics. Bat wings and human arms and whale flippers being homologous is objective biological fact
>In what specific way do these structures provide evidence for evolution
Think really hard on what you said about basilosaurus having teeny tiny legs and not being able to walk. You’re close to getting it
>gay whales have kegs
