Humans differ from other animals due to size and complexity of cerebral cortex: different functions require different structures, different shapes and sizes of homologous structures. The inheritance of behaviors: behaviors evolve naturally through trial and error. Genes: gergor mendel the father of modern genetics, research led to understanding of units of inheritance (genes, dichotomous traits: two forms (e. g. , blue vs. brown eyes, etc. ). Phenylketonuria (pku): single-gene developmental disorder: homozygous recessive genotype lack enzyme that coverts phenylalanine to tyrosine, which is a necessary step in normal metabolism, build up of phenylalanine results in altered development, severe developmental and intellectual defects. Inability to metabolize phenylalanine results in excessive levels: fidgety, irritability, hyperactivity, neurological dysfunction, seizures, low levels of neurotransmitter dopamine, gene by environment interaction.
