New Video
Added 2024-12-06 10:20:41 +0000 UTCHey everyone! The video for this week is done.
We're taking a look at three disputed species of animal. I really enjoyed researching all three of them and making this video, so I hope you enjoy it too!

I certainly agree with M. Ashby-Saracen that the Dwarf Manatee is speciating. It's clear that phenotypic evidence tends to preceed concrete genetic evidence (see Verne Grant, 1985).

It could be that the dwarf manatee is a species in the process of evolving and that given time, the genetics would "catch up" with the anatomical differences. Sadly, it looks as though scientific reluctance to give it such a chance might be one of the factors that leads to its disappearance.
