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 fuddle 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 fine-looking though the presence of its coded protein DUF1220. The actual function of this protein is non all in all 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 entrap that this gene is expressed in mammals but most signifi fundamenttly in primates (Popesco, 2006). The amount of expression of this gene has been plug in 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, can be used as an explanation to this phenomenon.
A typecast 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 during Metaphase I in Meiosis I. (Appendix C) Uneq ual recombination means that fractional of ! the end gametes allow for end up having more copies of a gene, in this gaucherie MGC8902, and the other half will drive home a pull down number of copies of this gene, who will be taken out of the...
