Document Summary
Chimps and gorillas can be taught to communicate non-verbally. The architecture of your brain affects your behaviour. Ke family pedigree showing specific language impairment (dominant mutation in the foxp2 gene) Pattern of inheritance suggests a single dominant gene. Human-specific transcriptional regulation of cns development genes by foxp2. Because foxp2 has an important role in speech and language in humans, the identified targets may have a critical function in the development and evolution. As seen earlier, organic evolution and genetic traits influence behaviour and in this case language and culture. Evolutionary changes in genes such as foxp2 and others facilitated language, which affected our culture greatly. Birds typically females disperse farther than males or both sex. Mammals typically males disperse once reaching maturity (e. g. deer mice) Increased risk of homozygous deleterious recessives: e. g. sickle cell anemia, e. g. human recessive diseases pku, tay-sachs disease, cystic fibrosis. Outbred: 1 copy of good allele, 1 copy of bad allele.
