Why is evolution considered a theory Brainly?
Answer: A scientific theory is a well-substantiated explanation of such facts. The facts of evolution come from observational evidence of current processes from imperfections in organisms recording historical common descent and from transitions in the fossil record.

How can embryonic development be used as evidence for evolution?
Embryology the study of the development of the anatomy of an organism to its adult form provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. … Another form of evidence of evolution is the convergence of form in organisms that share similar environments.
How is the fossil record evidence for evolution Brainly?
Answer: Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
