Defintions Flashcards
Microevolution
the change in allele frequency in a population over time ( generations ). Change in gene pool and species over time
Homeoplasies
Traits that are similar in appearance but have diff evolutionary origins, aka analogous features
Adaptive radiation
Process when divergent evolution occurs in rapid succession, or simultaneously, among a number of groups to produce three or more species, occurs when environment favours a variety of divergent traits
Embryological development
Embryos of closely related organisms often have similar stages of development.
Molecular biology
. If two species have genes and proteins with sequences that match closely. We can conclude that sequences must have been inherited from a relatively common ancestor. Amino acids become proteins
Descent with modification (evolution)
Descendants of earliest organisms spread into various habitats over millions of years, in these habitats they accumulated different modifications or adaptations to diverse ways of life. Example rabbits, snow rabbits are white and have thick fur. Brown rabbits camoflauge
