Such as skeletons and organs

Question 3

Physical characteristics of the primate group

Answer 3

180 degree arm swing

Large brains

If the solution percepitates a lot then they are closely related

Question 6

Behaviour

Answer 6

Similarities between organisms such as:
Rearing young
Social groups
Communicatio

Question 7

Different forms of evidence

Answer 7
