Q1 ? Darwin?s theory of indwelling selection states that some beings testament posses characteristics that be more fit to their environments than others. These organisms are more in all probability to survive and breed, thus passing on their characteristics to their offspring. During the first 7 generations, in which the forest was c everyplaceed in lichen, it was advantageous to the moths to be white so as to camouflage themselves on the run trunks. While Darwin did not know ab kayoed heterozygous and homozygous genotypes, they lifelessness contri s evinceed to the phenotype of the moths and thus Black moths still appeared after generations of ? race murder?. The best suited organism (most camouflaged moth) will prosper, but the disadvantaged organism (non-camouflaged moth) whitethorn not die out completely. Evolution of a species occurs due(p) to natural selection ? in this case the selection has been do depending upon the colour of the moth. Q2 ? The Gould/Eldridge th eory of punctuated sense of balance states that developing occurs fleetly followed with an extended period of calm. Reasons for a quick change take rapid climate change, new competition or ravage organisms. The Darwin/Wallace theory of evolution by natural selection leans towards a graduated evolution. This graduated evolution would imply more contrasting transition organisms throughout time and therefore, many transition fossils.

This is not so ? new, unique species appear in the fossil repose for periods of 5-10 million years before disappearing. both the Gould/Eldridge and the Darwin/Wallace theories attr ibute evolution to natural selection and spe! cies specificity but slice Darwin/Wallace say that organisms are continually evolving, Gould/Eldridge say that evolution in an organism is a relatively rapid event, occur over a a couple of(prenominal) generations in response to a drastic change in environment. After the initial evolution period, the organism remains suitable to environment until next change occurs. Q3 ? The Moth pretence supports both...
