Biological species - same species if members mate and produce fertile offspring under normal conditions 2. Species can evolve through natural selection a) Sources of variation 1) Mutations - DNA substitution, deletion, and insertion 2) Migration - move to another location 3) Recombination - meiosis, crossing over 3. Speciation a) Reproductive isolating mechanisms 1) Mechanical, behavioral, gamete isolation, time isolation, hybrid inviability b) Modes of specitation 1) Allopatric (isolated location), parapatric (transition area), sympatric (others - ecological, behavioral, etc.)
