Document Summary
Selective breeding: agricultural crops, could artificially select plants for specific traits, trying to get highest yield from crop, crossing plants with other plants to get desired (cid:862)offspri(cid:374)g(cid:863, genetic engineering, ex. Rice: rice with a precursor to vitamin a: ex. Round up: herbicide that kills weeds but not plants: soybeans, canola, cotton, maize. Nature vs. nurture: behaviour of simple organisms is driven more by genetics than learning, although environment plays huge role and are able to learn, a lot is complex and innate and. Learning plays a greater role in complex organisms such as humans and primates.

Innate involuntary stimulus response: can be simple reflexes or come in complex sets (cats landing on feet if dropped) Human adult reflexes: breathing, shivering, eye blink, hand withdrawal, startle response, knee jerk, salivation.
