Where Did Orcas Come From?
It should be noted that the phylogeny of many of
these organisms is very controversial due to the many definitions of
what a species is, so there are many differing opinions about the
origin of Orca whales. It should also be noted that many of
these branching points are much more extensive than I went into, but
I decided to only show that information that seemed pertinent to the
phylogeny of Orcas.
