Answer:
1. The pieces of evidence that support the theory of evolution include the following:
a. Fossil records/evidence
b. DNA of the organisms
c. Comparative anatomy
2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.
3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.
In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Macromolecule are large molecule consisting of a long chain of monomers that are joined or linked together. examples include protein,nucleic acid,amino acids.
Answer:
The action of the shifting continental plates of Earth has important effects on the course of speciation of living organisms by reproductively isolating populations or allowing previously separated populations to interbreed..
Explanation:
The formation of geological barriers such as mountains special cause of allopatric type, these barriers cause isolation which prevents two or more groups from mating each other regularly and finally there is speciation. On the other hand the movement of continental masses for example can cause the union of islands that allows a new genetic crossing between populations.
