Natural Selection

Within a popultion and due to competition between individuals, those individuals with an advantage will survive to pass their genes on to the next generation

The movement of tectonic plates influences evolution by

The fossil record represents 99% of all species that have ever existed


When local environmental conditions change, species may become extinct through background extinction


Selective breeding is a method of artificial selection


Geographic isolation and reproductive isolation are the two processes that affect the number and types of species on earth


In speciation, two species interbreed to form one new species


Exctinction is the permanent loss of genetic diversity


Mutations are beneficial


Evolution comes about only through the process of natural selection


Survival of the fittest refers to those individuals that leave the most offspring


Genetic engineering involves making a modified gene, making a transgenic cell, and then growing a genetically altered organism
