متن کاملHow Symbiosis Can Guide Evolution
Hinton and Nowlan have demonstrated a model of how lifetime plasticity can guide evolution. They show how acquired traits change the shape of the reward landscape in which subsequent genetic variation takes place, and in so doing encourage the discovery of equivalent heritable traits. This enables the seemingly Lamarkian inheritance of acquired characteristics without the direct transfer of inf...
متن کاملExtended genomes: symbiosis and evolution
Many aspects of an individual's biology derive from its interaction with symbiotic microbes, which further define many aspects of the ecology and evolution of the host species. The centrality of microbes in the function of individual organisms has given rise to the concept of the holobiont-that an individual's biology is best understood as a composite of the 'host organism' and symbionts within...
متن کاملSupertrees and symbiosis in eukaryote genome evolution.
If we took all of the single copy genes in all sequenced genomes, made phylogenetic trees from them individually, and then made the supertree of those trees, what would we get? Recently, David Pisani and colleagues did that experiment and their results are likely to spark much discussion. Their prokaryote tree looks very familiar, but the genome history of eukaryotes appears dominated by genes ...
متن کاملEvolution of mutualistic symbiosis without vertical transmission.
Mutualistic symbioses are considered to evolve from parasitic relationships. Vertical transmission, defined as the direct transfer of infection from a parent organism to its progeny, has been suggested as a key factor causing reduction of symbiont virulence and evolution of mutualism. On the other hand, there are several mutualistic associations without vertical transmission, such as those betw...
