Struggle for existence everything needs to work at trying to survive and compete with each other/ other species. Carrying capacity maximum number of organisms that can be supported on a specific unit of land. (how many people can be supported before there are issues) Stabilizing selection - when there is no longer an advantage. Natural selection: in any population those individuals with advantages over others will have the most, healthiest and fertile kids. How to see if they"re the same species. Phenotype = appearance (observable and measureable traits of two animals) Comparative embryology = compare embryos (are they the same species) If species threshold is over 1% the(cid:455)"re different species.
