Q1 ? Darwin?s theory of indwelling selection states that some beings testament posses characteristics that are more suitable to their environments than others. These organisms are more belike 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 maneuver trunks. While Darwin did not know ab kayoed heterozygous and homozygous genotypes, they still 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) may not die out completely. Evolution of a species occurs due to natural selection ? in this case the selection has been made depending upon the colour of the moth.
Q2 ? The Gould/Eldridge theory of punctuated sense of balance states that evolution occurs swiftly followed with an extended period of calm. Reasons for a quick change include rapid climate change, new competition or predation organisms. The Darwin/Wallace theory of evolution by natural selection leans towards a graduated evolution. This graduated evolution would imply more different transition organisms throughout time and therefore, many transition fossils.
This is not so ? new, unique species appear in the fossil record for periods of 5-10 million years before disappearing. both the Gould/Eldridge and the Darwin/Wallace theories attribute evolution to natural selection and species 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 few 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...
