BIOL 121 Lecture Notes - Lecture 8: E. O. Wilson, Ecosystem Diversity, Genetic Diversity
Document Summary
Each species is adapted to a set of environmental conditions. Dehydration: loss of body fluids (water) below normal range. Pads on feet for walking on hot so: sand toes spread out for better grip. Long thick eye lids with double lashes reduce sand in eyes. Hump: storage area for fat [food] supply in times of need. Thick (tough) split lips to eat thorny desert plants. Thick fur insulates body against extremes of heat [during day] & cold [at night] and camels regulate body temperature. A measure of the variety of life.
