PPT-Becoming Human: Evolution of pair-bonding

Social systems of our primate relatives Old world monkeys Female bonded groups Gibbons monogamy Orangutans exploded harems Gorillas true harems Chimpanzees bonobos multimalefemale groups malebonded groups. Variation in Living Things. SPECIES  - Group of organisms that interbreed. VARIATION - small differences between individuals of a species  . Some neither helpful nor harmful  . Some enable organism to be better suited to its environment.. Valence Shell Electron Pair Repulsion Theory. (VSEPR). Electrons can be placed in two categories. . Bonding pairs. [involved in a bond] .
