Evolution
Evidence
Anatomical structures
Understanding similarities in physical features helps establish a basis for a common ancestor and therefore proves evolution

-
Direct observations
Observing first hand small-scale evolution within organisms that have very short lifecycles(bacteria)
Mechanisms(fingers)
-
Nonrandom mating
choosing a mate based on a certain desirable trait that changes the gene frequency over time; certain phenotypes are preferred causing their counterparts to die out in offspring
Mutations
changes in genetic DNA sequences causing a change in a gene; changes how certain poly-peptides functions; affects survival of individual, ultimately changing the frequency of a gene within the gene pool
-
Gene flow
relates to migration; significant fluctuation of new arrivals/departures from/to a population; gene frequency in gene pool is affected
Adaptations
advantageous traits that allow an organism to thrive, while disadvantageous traits become obsolete eventually
