How Are Animals Related? - The Family Tree of Life

Описание: Animals come in a huge diversity of shapes and colors. But are they all related? How would we even know that? Let's look at the family tree of Life! Please subscribe to continue learning what makes life AWESOME: https://BioBush.tv/subscribe

We can't ask animals about their family tree. Even if we could it's unlikely that they would know who exactly their Great * 1 million grandparents were. So we use a different mechanism, which is mutations. DNA mutations happen regularly in animals, and some are passed on to their children (and their children's children, etc.) So any animal with a particular mutation somehow got it from the original mutant grandparent.

By looking at lots of mutations we can rebuild the order of splits that led to the family tree being formed.

This video clearly explains the concepts of building an animal family tree and has animated examples and demonstrations. I hope it gives you some new insight into how we know that animals are related!
