Hi!

I can do Homologous structures and vestigial structures

Homologous structures are similar bone structures in very different species, like whales and bats. We use this to see how we evolved alongside other animals with the same common ancestor.

Vestigial structures are structures we don't need anymore, like our tailbone. We can use these to tell how our ancestors lived and what they needed to survive.

Hope this helps!
