Can someone help me with this

a. The biggest change that we see here is the size of the skull, and how the jaw and forehead changed as time went on. There may be small details of change that we cant see without the skulls in front of us. also the hove, that is a major change as well

b. Again we can see the the size of the bones, but i think that a big change would be the hove because that i think was the most dramatic

c. Well some similarities are the shape of the skulls head, , also the jaw looks the same is the first 3 pictures, but the last two had the most dramatic change as time went on. we can also see that the eye socket looks the same through out, i know it changed in size but it looks the same

Explanation:

I took equine, so i know about this. I don't know everything but i know enough
