Document Summary
It can result in genetic mergers and increase the complexity of a system. 2 different organisms with 2 different genomes merge as one. Transition from prokaryote to eukaryote was very important as a result. 2010 biologists from scandinavia on a northern exploration. Big instrument and drops 3000 km into ocean and brings up a chunk of ocean floor and bring on board. Sequence all the dirt extracted: extract dna, next generation sequencing of the dna, assemble the dna-sequencing data, genome sequences from species in sample. Some of the genomes belong to a new lineage of archaea. Genome data hint at organism that has dynamic, actin-based cytoskeleton, vesicular trafficking, and membrane-remodelling capabilities, and potential for uptake of materials from environment by endocytosis and/or phagocytosis. Published - complex archaea that bridge the gap between prokaryotes and eukaryotes. Gene loss of the host and bacterial endosymbiont. Eukaryotic life was a genetic merger between alpha-proteobacterium and loki.
