Why do you think the birds and crocodiles are closely arranged on many evolutionary trees?
CFS:
student describes the relationship between anatomical similarities and differences in animal species
student describes the chronological difference between animal species with a common ancestor based on body structures

Question 2
2.
Birds and crocodiles are closely related to each other on many evolutionary trees that include all species and organisms. What does this tell us about their structures?
Since birds and crocodiles are closely arranged on evolutionary trees they must share many common structures.
Since birds and crocodiles are closely arranged on evolutionary trees they must live in the same exact environment.
Since birds and crocodiles are closely arranged on evolutionary trees they must eat the same food.
It is not possible to tell in such a close image of the evolutionary tree.
Birds and crocodiles are closely related but have clear differences today as well including size, and prey. What is a factor for these differences?
They had a common ancestor that’s population mutated in the same environment allowing adaptive traits to survive.
They had a common ancestor that’s population split and was separated into two environments, mutations and traits continued to reproduce if they were adaptive traits.
Birds and crocodiles are related, but scientists are not sure why because of missing fossil information.
There's not enough information to come to a conclusion.
