Document Summary
All livings organisms are composed of cells or products of cells. Hence, all cells are derived from other cells therefore, there is no spontaneous generation. (5). Define evolution: it changes in gene frequency in population across time. Natural selection operates on the individual: dobszhanky quotes, nothing in biology make sense accepts in the light of evolution. Evolution is connecting thread to everything* (a) we live on a dynamic planet and species must constantly adapt to changes in abiotic and biotic conditions. Define adaptation: a heritable characteristics that enhances an individual"s survival probability and its fitness potential. Define fitness: number of individual genes passed into subsequent generations in comparison to other individuals within a population. (b). It is a proportion of specific genes and their alleles within a population. Define alleles: variant copies or types of a gene. Define genepool: all of the genes and their alleles for a population. Type a- is primordial ( at about 10 mybp)
