Question

Substantiate the idea of evolution through molecular evidence.

Answer 1

Homologies: cellular/molecular evidence. All living things are fundamentally alike. At the cellular and molecular level living things are remarkably similar to each other. These fundamental similarities are most easily explained by evolutionary theory: life shares a common ancestor.

Answer 2

Substantiation of the idea of evolution through molecular evidence is followed by:

• Across generations, changing in sequence composition of DNA, RNA and proteins (cellular molecules) is called molecular evolution.

• The principles of evolutionary biology and population genetics are used in this field.

• Example of an evidence is Darwin's original hypothesis of common descent.
