Document Summary
List the major transitions in the evolution of life on earth. The evolution of eusocial structure: describe the three processes that occur during these transitions. Each major transition includes at least one of the following: once individuals aggregate into higher-level groupings, they can take advantage of. Individuals give up the ability to reproduce economies of scale and efficiencies of specialization: aggregation and specialization facilitate changes in information. List the steps of a major transition and give an example of how it would be difficult to reverse. Incentives for selfish replication do not outweigh the benefits of cooperation and coordination and higher-level organism get locked in by some aspect of their biology (eg. genetic imprinting. 12. 2 major transition: the evolution of the eukaryotic cell: describe the lines of evidence supporting the ideas that either archaea or bacteria were the most recent common ancestor of the eukaryotes. Early studies suggest that eukaryotic cells may have arisen from bacteria or archea.
