Evolution: It's a Thing - Crash Course Biology #20

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

When I was 5, I saw my parents leaving my Christmas presents under the tree, I kept believing in Santa for a couple of more years, it was just more convenient.

Well you don't need to apologize, it only was a tip to consider.

In (the heat of) a debate pointing someone to spelling skills could easily interpreted as an argumentum ad hominem and spoiling the discussion unnecessarily.

Butterflycaught, I think they just filled in "natural selection" in the multiple choice while believing it was "faith" just to increase their score on the biology test, salary at work, and quality of life for their families. Smart but not 100% smart until your heart is in the facts.

Thank you all for all the debate in the comments. I thoroughly enjoyed reading it.

You misunderstand. I'm an atheist. I mention these people out of genuine cuiosity. I literally can't understand how they believe the bible despite knowing so many of the facts of life.

[GmMkr]

Eh, look. Before you list the other 5 or 6 that likely exist, let me ask you: does it matter? Even if these people exist, you can't take their ignorance of the facts as evidence of anything. If you're saying that because these people exist, then that's some sort of evidence, then I use the other 99.98% that agree with evolution as my evidence.

Of course, this isn't how it works, but if you want to play the numbers game...

I must admit, that is a nice try. I had to do quite a bit of digging before I actually found anything on him that didn't come from that genesis site. He has a PhD in Anatomy. Sorry. Doesn't count. But, I'll admit. It's amazing that he has a PhD in any scientific field and still manages to hold on so tightly to his ignorance.
