Modern animals have only been around for a short time compared to some ancient species When you think about how long dinosaurs or early sea creatures lived it really puts into perspective how new most animals today are

It’s pretty cool to realize that all monkeys and apes are grouped together as primates It makes you think about how closely related they all are, despite their differences It also reminds me that as humans we’re part of that same group which is pretty wild to consider

This part is interesting because it shows how small DNA differences can explain why we're so similar to some animals but completely different from others. It's wild to think just a few changes in nucleotides could be the reason we’re humans and not chimps or dogs. I wonder how much of that difference is responsible for things like intelligence or language
