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.

How many people other love scrolling through the comments and seeing people cursing at each other about God and evolution?

I am a giant iguana and i support this video.

I wish I lived in a world where a video like this didn't trigger people

My biology teacher doesn't believe in evolution, so I'm watching this video to get some points to bring up to her.
yes. My BIOLOGY teacher.

Accepting microevolution but rejecting macroevolution is like accepting that 1+1=2 but rejecting that 1+1+1+1+1=5.

Studied 11 years in a Catholic school in Brazil where evolution was sanely taught as fact. Absolutely shocked to realize the overwhelming American denial of it.

I love how Hank just sounds so tired of evolution deniers 😂 hes just done with everyone

Say it with me, people, populations evolve, not individuals.

Don't be hard on those religious people who find it hard to grasp Evolution as a concept. I have a Christian friend who is extremely open minded, but she is young and new to these ideas. When you have spent your entire life in churches and around other Christians who are endlessly backing up your beliefs, it's hard to even find the opportunity to find out any other information.
After talking to her about Evolution she asks all the right questions and accepts fact as fact, but I can see on her face that it is conflicting with her own beliefs so it's hard to process this.
If I were to yell angrily at her and call her stupid for not understanding, I would just be encouraging this processing of beliefs to cease - forcing her to return to her religious beliefs.

Real discussion can lead more people to understanding this idea. Arguing and bickering will just make the divide wider. So if you really care about spreading knowledge then please consider your approach to the matter.

There may be some religious people out there who are UNWILLING to accept the idea, but so are there many non-religious people who are stubborn and unwilling for change in their life, so we can't really blame them.

I hate when people say "I believe in evolution" or especially "I don't believe in evolution" Its not a matter of belief! It is a matter of accepting the reality of what's going on around you.

This is the most toxic comment section ever haha. Love the video Hank. Good job.

The worst about creationists is that you can't argue with them without feeling like running against a wall.
No matter how diversified your arguments are, they will always come up with god and think of this as the perfect counter-argument.

Hey Hank and the SciShow Crew,
I'm an Accelerated Biology teacher at an upper middle class public high school in the Chicago suburbs. Last week was unreal. I had assigned this video for my classes to watch as a preview to our discussion of this topic. I received a complaint about the content and was asked by a parent if her son could complete alternate assignments to represent his own "worldview" of alternate "scientific theories" about the origin of life. Lest a parent complain to our Superintendent, my Department Chair and I offered apologies for this inappropriate material (specifically the first two minutes, where you justify science as a thing). Thankfully, we live in a state that has adopted NGSS standards and were unable to offer alternate assignments. Just WOW!

"... there are two sorts of people in the world. Those that are excited about the power, and beauty and simplicity of the process of evolution, and those who don't understand it."

Very well said! :)

My dad is a Christian and when I told him Evolution is real he says "it's not real, Evolution is a Manmade process" I did not respond just looked at him with a face saying wtf

If we came from Europe, why are there still Europeans? Checkmate historians

[glueee]

Hard to believe that evolution is still controversial.

Comments section was exactly what we all expected.

Silly darwinists we didn't evolve
We where created by the Flying Spaghetti Monster
