Great episode and I'll study this in the second part of my biology undergraduate.
i wonder if it would be possible to artificially genetically isolate dogs enough to the point where they become different species…

As a 7 grader thx
Lemon and Addie are the cutest
that is indeed a most awe-inspiring Napoleon Dynamite costume
I wish good luck to Hank
4:30 I was really expecting that to be followed by “and not the British for ‘hello Patrick’”
Just remember that, in allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. In sympatric speciation, groups from the same ancestral population evolve into separate species without any geographical separation.
