Document Summary

Lecture 1: domains of life had a universal ancestor, but now have multiple ways to grow, reproduce, move. Gae 1: no organism is more advanced than another if they both are on one tree. Can be considered to show more primitive traits. Lecture 3: dna mutates slowly, and in certain places more than other. People (woese) track these changes to try and connect the domains of life with phylogenic tree. Lecture 4: life started with energy, reproduction, info, rna because prone to error therefore likely to cause evolution and acts as an enzyme to catalyze reactions. Gae 2: light is highly usable form of energy but not heat. Energy enters a system as light, leaves as heat. Lecture 6: to make and use energy there are many different options (phototroph, chemotrophic, autotroph, heterotroph) and there may be evolutionary benefits to each.
