Document Summary
Organic material in the bone: collagen - eventually mineralizes and turns into fossils. Make empirically based inferences on dead species from still in the present. Uniformitarianism - natural disasters are consistent over time, the processes that occur in the present occurred in the past. Can make inferences because the processes is the same from back in the day and now. Where the spinal cord enters the skull. The relative length of the forearm is longer = hanging from branch.

Three theories on primate origins: fred szalay: arboreal theory. Came from a shift of eating insects to leaves. Does not explain depth perception: matt cartmill: visual predation theory. Hunting insects on terminal places on trees. Depth perception is incorporated in this: robert sussman: angiosperm co-evolution theory. Taking advantage of fruits on angiosperm plants.
