Brain mind behavior consequences evolutionary selection genes brain: you can start anywhere in the cycle. Dar(cid:449)in"s principles of e(cid:448)olution: organisms produce more progeny than can survive, sexual reproduction = genotype variation (alleles, genotype variation phenotype variation (traits, traits are inheritable, environment selects for particular traits, different traits cause differential reproduction. Types of selection: directional selection, moves the entire range of the population either higher or lower; shifts means i. e. ) It is convergent evolution when there is a homoplastic trait, which is a trait shared due to convergent evolution i. e. ) trap jaws. Chromosomes are the structure of nucleic acids and proteins that contains genes, i. e. a strand of dna molecules. Nucleotides are the building blocks of dna or rna; they determine which proteins will be manufactured by the cell.
