GREATEST GLOBAL BIODIVERSITY: VIRUSES. "The oceans are being viewed as a vast reservoir of potential genetic and biological diversity that can be interrogated to uncover processes and functions. Perhaps surprising to some, most life in the oceans, by weight, is microbial." https://lnkd.in/e2MHV6z View in LinkedIn

GENOMIC BEEFING UP. "The ancestral eukaryotic gene repertoire seems to have approximately doubled in size before the onset of the major eukaryotic radiations." http://www.biochemsoctrans.org/content/41/1/451.full View in LinkedIn

"MASSIVE GENE DUPLICATION at the basis of the eukaryotic emergence. The existence of a large amount of pan-eukaryotic paralogues suggests that gene duplication has been a major driving force in eukaryotic evolution. For example, whereas many components of the eukaryotic core machinery comprise two or more gene copies, their prokaryotic counterparts mostly contain only a single gene."

PROK TO EUK TRANSITION. "The evolutionary transition from prokaryote to eukaryote has been a complex journey in which non-tree-like processes have probably played a decisive role." http://www.biochemsoctrans.org/content/41/1/451.full View in LinkedIn

THIRD CONSENSUS. "A significant fraction of the eukaryotic genes encode proteins that are restricted to eukaryotes, the so-called ESPs (eukaryotic signature proteins)." http://www.biochemsoctrans.org/content/41/1/451.full View in LinkedIn

SECOND CONSENSUS: "eukaryotic genomes have a chimaeric nature: genes for information storage and processing are archaea-related, and genes for metabolic or ‘operational’ processes are mostly bacterial in nature (but not necessarily derived from the mitochondrial progenitor)." http://www.biochemsoctrans.org/content/41/1/451.full View in LinkedIn

FIRST CONSENSUS. "The evolutionary origin of the eukaryotic cell represents an enigmatic, yet largely incomplete, puzzle...some consensus has been reached about the following points: first, the LECA (last eukaryotic common ancestor) most probably contained the mitochondrial progenitor derived from endosymbiosis with an alphaproteobacterium." https://lnkd.in/ewbMda5 View in LinkedIn

SYMBIOTIC VIRUSES. "Viral persistence in host organisms is crucial because they reliably protect the host against similar parasites. Interestingly, competing viruses are in most cases of the same or related species, whereas unrelated viruses do not compete but interact symbiotically." https://lnkd.in/e-pJFM6 View in LinkedIn

SESSILE LIFESTYLE. "Persistent viruses are capable of continuous or episodic reproduction in the hosts. The main direction is not to infect cells for reproduction with lytic consequences and often epidemic viral diseases, but a sessile life-style without harming the host." https://lnkd.in/e-pJFM6 View in LinkedIn

ENGINE OF EVOLUTION. "Hybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations." https://lnkd.in/emnTG9f View in LinkedIn
