Meaning of species Evolution of species. Speciation process. Proof to ascertain speciation. Natural selection.
Birds developed from a two- legged running dinosaurs called theoropods. Every component of a bird has develop to enable them to fly. Over 10,00 kinds of birds have the ability to fly Two birds that are incapable to fly are the ostrich and the penguin.
Birds breed with different species of birds and become a new species. Genes. Geographic position. Sexual selection.
Non-genetically bases changes of mate Various species of one bird
Variation-difference in look and behavior. Inheritance- characters from parents are transferred to their offspring High rate of population growth- some reproduce more than others Differential survival and reproduction- individuals learn processes that will help them with the fight for local resources and will produce more offspring.
Explained species. Evolution of species through time. The method of natural selection in species. Speciation device
