2. a. The existence of significant difference between fossils of living things from different points in time
b. The similarities in the body structure, between living organisms of a given category, at the early stages of development, and the different application of the body structures as they grow
Explanation:
1. The concepts given in the paragraph are;
i) Studies in fossil observation, indicates that a difference exist in the fossils of living organisms at different historical times
ii) The similarities observed in form of existence of animals of a particular type at a given stage is an indication of common ancestry
iii) The arrangement of body parts of animals having different body structure, indicates that the animals have a common ancestries
The true statement is therefore;
b. Animals that develop with the same pattern share a common ancestor
2. The evidence that supports the theory of evolution are;
a. The existence of significant difference between the past and present living organisms is observable by the study of fossils
