Answer:
1. b. Animals that develop with the same pattern share a common ancestor
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
b. The similarities of the early stages of animals with backbone and the differences in the functions of the bones while still being in the same order of arrangement.
