Document Summary
80% of the recombination occurs at 10-20% of sites in the genome. Loci in between hotspots that will most likely be feound together. Able to conserve honey when flowers aren"t blooming. Previously assumed that lowland and highland were two separate subspecies. Genetic differences were low, consistant with them being a single, panmictic (interbreeding) population. Key properties of life: homeostasis, structural organization, metabolism, growth and reproduction, response to environment, subject to and evolves through natural selection. Earth surface was hotter - 80 degrees celsius. Atmosphere cmposed of co2, nitrogen, ammonia, methane, co etc. Phylogenetic reconstruction is limited when considering the origin. Point in the history of life beyond which phylogenetic analysis cannot see. Luca is the last common ancestor of these three life forms. Warm little ponda protein compound was chemically formed ready to undergo still more complex changes - darwin. Pool of molecules in prebiotic soup augmented from outer space. Meteorites, comets, and interstellar ice raining down on earth.
