[00:00:02]Oh my god.

[00:00:22]We all don't like doing that.

[00:00:26]I this I need the resistance to be different.

[00:00:30]I don't know if I can do it so far down.

[00:00:46]Follow me.

[00:00:47]Guys, this Go home. Hey.

[00:00:52]Go home. Move it back.

[00:00:54]Please, go home. I'm going to hit you.

[00:00:57]Go.

[00:00:59]They can be just flowing off in the lake or grazing throughout the valley in large groups or herds.

[00:01:12]Follow me. Follow me. Guys, this Look, do you know what?

[00:01:39]Just like a minute ago, so Good afternoon.

[00:01:59]I did. Yeah.

[00:02:06]>> Well, T-Rex is an extreme among extremes.

[00:02:11]It's an outlier among outliers.

[00:02:15]Its entire family is very weird. The Tyrannosaurs have very strong heads as a whole.

[00:02:24]And they are relatively big, but they were still, compared to T-Rex, quite fast, quite agile animals.

[00:02:33]T-Rex took that idea of a massive predator with a strong head and smaller arms and kind of went into overdrive because it I think I'm right saying it was probably the only giant animal for thousands of miles. When we say that an animal only has a certain budget, so an energy budget is like how much it gets in from food every day.

[00:03:00]So, that because there's only a certain amount of food energy that an animal can take in, there's only so much there is to go around.

[00:03:08]And if it needs all of that energy to maintain its equipment for hunting, like a very strong, very heavy skull, it doesn't really want to Evolution doesn't want to use it for anything else.

[00:03:21]So, it kind of says, "Okay, we'll take away from the arms because the arms aren't really much use to us anymore.

[00:03:27]They're not using them as a hunting hunting uh thing.

[00:03:32]We'll put all of that energy into growing a bigger, stronger skull." I don't know how likely that is cuz you're trying to lift up an 8-ton animal with arms no bigger than a human.

[00:03:42]It's like that's interesting, but it's it's something that is a scientific hypothesis that could be tested.
