evolution test

populations that evolve have a common ancestor

Organisms better adapted to their environment tend to survive and reproduce more offspring ex white and black moths

fossil record, molecular biology, comparative anatomy, embryology, Vestigial structures and biogeography

looking at fossils and evidence in bones to see similar structures between related organisms to see progress of evolution

genes in an organism can be compared to determine how closely related there

same body parts of an organism are analyze for similarities

same parts are used for the same function and come from a common ancestor

parts used for the same function but come from a non-common ancestor

comparative anatomy where embryology of organisms are study before they hatch, can see structures that are lost from their mature

structures in anatomy which are reduced or non-functional as they no longer contribute to fitness but provides evidence of the relationship between the species

The study of the distribution of plants and animals in the process that determines the distribution

macro evolution is major changes you see in a species that allow it to be defined as a different species from another and microevolution evolutionary change within a species over a short period.

populations can no longer interbreed with each other they become separated and reproductively isolated

physical barriers like rivers or mountains

temporal barriers like timing of flowering

mutations are caused by mistakes during replication of DNA

Random change in frequency of a gene

natural disasters or organisms producing more offspring than others when no section against them

happens as individuals migrate between populations of a species to reproduce

wolves migrating between packs

drastic reduction in population size and many alleles are lost

only a few individuals colonize a new environment Islands from the mainland population

happens when organisms select mates based on specific traits they possess

p2 +2pq + q2 = 1
