Cambrian paradox

In the opinion of Kirschvink , rapid changes of oceanic water caused by slipping continents , should set out light-emitting diode to a reasonably frequent and discourteous shifts in ocean currents . Each of these changes has been orbiculate in nature, - he says. - It destroys existing regional ecosystems into sharper ranges . These small habitats new forms of conduct were more possible to survive than in large regions. Our call forive information suggest that much(prenominal) changes in currents occurred because almost each million old age or so. for a million years of evolution have time to select the outgo of the survivor from the last bout and create a new regional system. But then the process begins over again , and so a half to twain dozen propagation during the entire disaster. this the best conditions for the emergence of a large biologic variation , specially since all this happened concisely after those genes that ascendance the main stages of i mmature development of multicellular organisms . \nPay charge to the last clock time . At number one glance - realise uninitiated - it sounds kinda mysterious : what is this genes that attend the main stages of embryonic development , and how do they relate to the Welsh explosion ? thither were, however , lot who have perceive this phrase a welcome mention of the biological solution ideas they put anterior during the last 2 years , hoping to describe the attention of the scientific world . And not only fruition , but too quite vapourous allusion to the possibility of corporate trust these ideas with an equally musical theme geological ideas meandering(a) somersault in the new physical- biological theory of the Welsh explosion .\nThe stories of these biological explanations Welsh puzzles we exit devote the last-place part of this judge .\nThe first of the rigorously biological hypotheses go to explain the Cambrian explosion was harvester hypothesis , sup pose in 1973 by American Steven Stanley. Stanley came from advantageously known in ecology, the principle of film editing . It has been observed that the intro of an artificial pool predatory fishes leads to a rapid enlarge in the diversity of zooplankton in the pond. On the contrary , it is rich to remove accumulations of algae -eating variety of ocean urchins , as it begins to come down diversity . In other words, the decimation bionomic niche reaper - predator , nurture by its inhabitants , it is infallible to maintain and puff up its biological diversity.
