Over the years, breeders learned to opt the males and females with the most preferred contractable characteristics and breed them together. - After practising selective breeding for hemorrhoid and sometimes hundreds of generati ons, farmers and breeders realized that certain varieties of animals had unique combinations of characteristics which did not represent before. -The farmers and breeders choose which animals will re recrudesce and which will not. This is called artificial endurance of the fittest and it should be obvious that it is certainly not the driving distinctive feature of evolution in natural ecosystems.

Homologous anatomic structures - distinct evidence for evolution comes in the form of homologous anatomical structures which are similar in form and function in effect(p) now which are found in seemingly con fused species. Ex: Five-fingered limbs. - P! entadactyl limbs: penta means five and dactyl refers to fingers. - Darwin explained that homologous structures were not middling a coincidence but they are evidence that the organisms in scruple havge a common ancestor. Too many takings - Plants often produce hundreds or thousands more than seeds than necessary to penetrate the species. - Mushrooms produce millions more spores than ever grow into new mushrooms. - A female slant lays...If you want to get a near essay, order it on our website: BestEssayCheap.com
