The popular play Inherit the Wind told the story of a school t apieceer who was to be jailed for t each(prenominal)ing training in the classroom and pitted the two greatest lawyers against each other. A popular slogan from the anti-evolution group was ?I didn?t come from an ape!? The slogan should birth been ?I sport more MGC8902 than an ape!? In the neocortex of the brain, ?the region that is stimulate for consciousness, language, and other higher(prenominal) cognitive functions? (Than, 2006), the expression of the gene MGC8902 is puffy though the presence of its coded protein DUF1220. The actual function of this protein is non whole known, barely it is speculated to be related to higher orders of thinking (Than, 2006). such thinking is, but not limited to, emotions, language, and reasoning. From an evolutionary standpoint, it has been catch that this gene is expressed in mammals but most importantly in primates (Popesco, 2006). The amount of expression of this gene has been yoke up to the level of higher cognitive function. This expression is controlled by the look of copies of MGC8902 in a specific genome (Bray, 2006). Therefore, the level of higher cognitive function is associated with the number of copies of MGC8902. Mutation, a mechanism of evolution, tush be used as an explanation to this phenomenon.
A character reference of genetic mutation is duplication, where a set of genes are not only copied but also replicated again in a copy of the genome. whizz explanation of duplication is unequal crossover voter during Metaphase I in Meiosis I. (Appendix C) Unequal reco mbination means that half of the end gamete! s allow for end up having more copies of a gene, in this gaucherie MGC8902, and the other half will deem a pull down number of copies of this gene, who will be taken out of the...
