Document Summary
Certain traits shared by each living organism on earth, all inherited by luca- genetic co de is universal (homology), all domains of life inherited these traits by luca - there is on ly one luca. How many ancestors: number should double each generation, at some pint pedigree collapses. If we go back far enough in time; any two individuals will share a common ancestor: rendezvous zero is the converging point between all humans (mrca of all humans) Rendezvous 1: chimps & bonobos: humans are equally related to chimps and bonobos, chimps and humans share a common ancestor; humans did not evolve from chimps they are cousins with respect to common ancestor. Rendezvous 2: gorillas: chimps, bonobos, and humans descend from the african great apes. Rendezvous 3: orangatuns: great apes converge to common ancestor with asian great apes, asian great apes are more solitary.
