the evolutionary history of a species or group of species is

When individuals with certain heritable characteristics will have increased survival and reproductive rates
What is Natural Selection
300
A change in allele frequencies in a population over generatons

300
similarities due to shared ancestor
What is homologies
400
The reason that different species have similar structures because of common ancestors
What is Homologous Structures
400
Average percent of loci that are heterozygouse

Way to assess allele and gene frequency
What is Hardy Weinberg Principle
500
defines a species as the smallest group of individuals that share a common ancestor, forming one branch on the tree of life
What is phylogenetic species concepet
500
Periods of evolutionary change in which groups of organisms form many new species with adaptions allowing them to fill new niches
What is adaptive radiations
