So here we're differentiating between typological species concept and the phylogenetic species concept.
00:08
Typological is an old system of determining of two organisms where the same species are not.
00:18
It is not based in evolution, not evo.
00:27
If there was type specimen, so a specimen that represented the species, and if you found a different variation of that species, a lot of times it would be called a different organism.
00:39
So let's say you have a butterfly that's usually as blue and black wings, but then you find a butterfly that looks very similar.
00:49
It has the same similar shape, same similar size, antenna is the same.
00:54
The patterns are the same, but instead of blue and black, maybe it's like a different shade of blue, like a light blue and black, or maybe it's even white.
01:03
Another good example is bumblebees.
01:06
They're patterns of yellow and black.
01:10
Not only do they change between species, but a lot of times they have tremendous variation amongst the same species...
