What is evolution? What species orginate from evolution and what species have remained the same?

growing can be applied to the origin of many an(prenominal) species firearm natural option provides a formula to consume the some suitable species in a particular habitat. rival challenges would remove each species to produce new defenses against diseases, climatic and against other(a) species in Macro bob upment. Micro evolution is the ceaseless genetic allowance and diverging distinguish feature among species and related species. Due to the indecorous geographic conditions and extensive time isolated would encourage more than diverse species to emerge, at the aforesaid(prenominal) time the ancestors credit rating would be less obvious with each successive species. convergent evolution in theory would encourage infinite contrary characteristics produced from the same ancestors. Natural selection theories reduce individuals differences while maintaining a high survival of the fittest rate for individuals who express advantages characteristics due to the ambiti on of survival inside the whole eco carcass. Analogy evolutions ensure contrasting species would develop from separate ancestors, so more varied species atomic number 18 unrelated and variety intra specification would in addition branch out from a particular ancestor. Captive rearing of related species cannot reignite antecedent species product due to prolonged length apart. Natural selection just refines the lottery system to provide a electroneutral field for all species to coexist.

phylogeny is the result of each species ancestors who pioneered their time to come generations destiny to change from being common to being alone(predicate) and become specialized. Convergent Evolu tion promotes similar abilities among genera! tions of species but sometimes they are not as obvious. The ocean surrounding Antarctica, fish go through a special trait which allows them to survive the big chill. As scientists discovered in the 1960s, the fish take away adapted by evolving a kind of antifreeze. (Atwood 1998) Its composed of molecules called glycoproteins that circulate in the course of the fishes. weight at the other end of Earth, in the Arctic, also have antifreeze proteins.
