Question

Evidence that best supports the theory of

biological evolution was obtained from the
(1) investigation of environmental niches
(2) study of fossil records
(3) comparison of the number of cells in organisms
(4) analysis of food chains and food webs

Answer 1

The answer is (2) study of fossil records.
This is because fossil records show relationships between organisms that may have evolved from each other, such as homologous structures.
Hope that helped you.

Answer 2

(2) study of fossil records

Step-by-step explanation:

As we know, fossils are records of organisms that lived thousands of years ago. Fossils are the remains of these organisms and can be used for various studies, in addition to being one of the main evidences of the evolution of species. This is because, through fossils, scientists are able to visualize characteristics of ancestral individuals and relate this to the form of life present on earth previously and the form of life present on earth today. Through this, they can see what characteristics of living beings have been modified over time, thus modulating how evolution happens.
