The correct response is this: NATURAL SELECTION FAVORED THE EVOLUTION OF LARGER BRAINS, THIS SUGGESTS THAT THE BENEFITS OF LARGE BRAIN OUTWEIGHS THE COSTS.
In fossils record, the shift from Australopithecus to homo is characterized by larger body and brain sizes and all through subsequent evolution, brain size has to continue to get bigger. The possession of large brain make man to be much more advanced in thinking than all other animals.
Gene, as such traits are passed down through genes
Answer:
Explanation:
Species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
Population: a particular group or type of people or animals living in a place.
Gene pool: the stock of different genes in an interbreeding population.
Mutations: the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
Lateral Gene Transfer: the movement of genetic material between unicellular and/or multicellular organisms other than by the transmission of DNA from parent to offspring (reproduction).
Single-gene Traits: when a trait is linked to one gene-pair that consists of two alleles.
Polygenic Traits: is one whose phenotype is influenced by more than one gene.
