What criteria is used to distinguish species would be biological species concept? reproductive isolation, diagnostic morphological features, monophylley, species -specific mate recognition mechanisms.
00:16
So what is the biological species concept? so this means that two organisms are of a different species if they are reproductively isolated from each other in any way.
00:28
So two species cannot interbreed.
00:34
So this works in a lot of cases.
00:36
There are a few flaws in it.
00:38
For example, there are cases where species can interbreed to produce completely viable and fertile hybrids.
00:45
So they're not reproductively isolated, but they might be geographically isolated.
00:50
There are also many organisms that reproduce asexually, which makes this very difficult to measure because they would never be interbreeding with anything.
00:59
So, what does this rely on? well, it relies on a reproductive isolation...
