Document Summary
Bio206 which our genes are expressed temporally and spatially-very sophisticated neural connections. Diversity: diff shapes and sizes of organisms. Structural similarity: dr. jane goodall: studies apes-chimpanzees, just by looking at the shape of the mouth- straightforward analogy- we can say that they are like humans. We use this gene as a marker for relatedness. Now we can analyze the entire genome (not just a gene) High degree of structure synteny genetic relatedness, genes at the exact same location in both. Identifying major groups of organism based on the analysis of genetic relatedness-suggestion is that they rose from a common ancestor-single cell type was the progenitor of all cell types and organisms that we see today. The record that we have is just of the survivors of the evolutionary processes. The common ancestor- would have had a radically diff metabolism because the earth would be unrecognizably based on what it is today.
