Document Summary
The muscle on your forearm/wrist that assists in grabbing things. What is the palmaris longus muscle: not all people have it; you can tell by touching thumb and pinky together. [pay attention to alleles and well as descent] Descent with modi cation: changes in organisms passed down generations. Nothing makes sense in biology, except in the light of evolution. Understand why evolution does not have to be progressive , deterministic or always increasing in complexity: evolution isn"t linear; more of a tree, evolution is random (mutations, complexity doesn"t increase. Physical evidence of species changing over time (i. e. birds/whales: supports our previous assumptions/helps us understand more about organisms, fish > amphibians > reptiles > mammals. What examples did we talk about: birds and whales, dinosaur/archaeopteryx > modern bird, animals with limbs/hooves > animals with ns. What are some examples of evolution in a relatively short time frame: bacteria evolving to survive medicine, moths during industrial era changing color.
