- The Origin Of Species
- speciation- the ones that split one species in two species and highlights the key similarities and differences between them
- microevolution- the change of time in allele frequencies of a population
- marcoevolution- the broad pattern of evolution above a species level
- species- members of group that have offspring only related to members of their own group
- definitively enhanced by reproductive isolation that blocks mating amongst certain groups leading to limitation of hybrids or interracial mating
- prezygotic barriers- block fertilization from happening by blocking members, preventing attempt mating or hindering fertilization, however if they fail postzygotic barriers occur
- classification of species: morphological species concept- characterizes a species shape by body type ecological looks at the species interacts with its behavior phylogenetic- group of individuals that share a common ancestor
- how does speciation actually occur? there has be to a disruption in the gene flow process first and then reproductive isolation occurs, causing the speciation
- speciation- the ones that split one species in two species and highlights the key similarities and differences between them
