Document Summary

One little alteration in the dna molecules. Ex: sickle cell >> common in high areas of malaria (those with sickle cell trait can survive malaria) Theory of evolution: change through time adaptation. Life is just trying to find its way . This allows us to understand the biological basis of our own behavior. At some point humans became more dependent on learning for survival than biology. Ex: horses walk right when they"re born. Natural selection the environment selects for and against certain variation in. Genetic mutation a dna point or chromosome section is altered by a random. Gene flow and drift statistical and event conditions increase or decrease. Evolution as adaptation error in the biological process characteristics success of a trait. Humans were created by god and divided at babel. Biology and instinct gave rise to higher consciousness and the ability to engage in independent and volitional choice in behavior.
