evidence suggests that living things have changed over time some fossils of long dead organisms show what certain species looked like long ago genetic testing also provides evidence to support the relationship between extinct and modern organisms does this information support a low or a theory



Answer :

A major unifying concept in biology is evolution. "Nothing in biology makes sense except in the light of evolution," Theodosius Dobzhansky once said.

Numerous branches of biology provide proof of evolution:

Anatomy:  Because a physical characteristic was present in the following common ancestor, species may have similar physical characteristics (homologous structures).

the study of molecules. The genetic code and DNA show how life has a common ancestor. Comparing species' DNA can reveal how closely related they are.

Biogeography :  Evolution and geological change are reflected in the global distribution of creatures as well as the distinctive characteristics of island species.

Fossils : The existence of species that are related to modern species but are now extinct is documented through fossils.

Direct perception: in creatures with brief life cycles, small-scale evolution can be seen directly (e.g., pesticide-resistant insects).
