Document Summary

The concept of egg and sperm, the concept of haploidy and diploidy. Darwin implants a very major in the thinking. Lamarck made us think that change was only happening to individuals. Darwin understands that changes are happening within a population; he makes us think in terms of population instead one individual changing and passing its traits on. Darwin sees organisms as full populations, groups of organisms in which there is an inherent amount of variability, consequently some organisms have better fitness transferred to the next generation (their genome and not the forms of another variant). Population genetics and natural selection are based on mendelian genetics: linking population genetics, natural selection, and mendelian genetics. Genes are in a population like alleles and that there is a mixture of alleles in a population. If allelic frequencies are found in a population, this indicates that natural selection has occurred. He does not have the mathematics to support the theory he proposed.
