Document Summary

All species share the same underlying mechanisms: storing energy, manufacturing proteins, transmitting information between generations. Large offspring, the best continue to survive. Favorable vs unfavorable traits according to the environment. Physical and biological environment does the selection. Large marine animals with similar lifestyles but different evolutionary heritages eventually tend to look the same. Carolus linnaeus: three supreme categories/kingdoms, animal, vegetable, mineral. Domains: prokaryotes single-celled organisms (no nucleus, bacteria, archaea, eukaryotes have nuclei and organelles, fungi, protists, animals, and plants. Life can capture, store, and transmit energy. Photosynthesis uses sun light as energy source: 1) starts with co2 and h2o (both inorganic, 1) then uses sun light to break bonds, 1) then produce carbohydrates (organic energy, 1) by product: oxygen (waste product) Chemosynthesis uses food as energy source: 2) starts with co2 and h2s (hydrogen sulfide, 2) uses heat or sun light to drive the reaction, 2) produce carbohydrates, 2) by product: sulfate (sulfur oxidizing bacteria)
