REGENERATION MEMORY. "When the limb of a salamander, or the liver of a mouse, is partially amputated, the remainder regenerates to its normal size and shape even though the context in which this regeneration occurs is very different from that in which the structure developed initially." http://www.pnas.org/content/95/7/3685.full View in LinkedIn

CONTRARIAN VIEW. "It is proposed that light can be shed on these questions by viewing evolution and organisms as natural processes contingent on the second law of thermodynamics, equivalent to the principle of least action in its original form. Consequently, natural selection acts on variation in any mechanism that consumes energy from the environment rather than on genetic variation." http://rsif.royalsocietypublishing.org/content/11/94/20131017 View in LinkedIn

FRAGMENT FROM NATURE concludes this weekend on the theme of competition and resource allocation. At all levels of living creatures, from different species in ecosystems — from identical populations, from individual organs, from the cells within the body, from the ecosystem of organelles in cells, to the very genes — there is evidence of competition for key limited resources. These nested hierarchies of communities of living parts all appear to play out a dance between natural selection versus preferential resource allocation. View in LinkedIn

NEW CRITERION OF SELECTION. "We conclude that the least-time free energy consumption in respective surroundings, as the general criterion of natural selection, determines also sexual and asexual modes of reproduction." http://www.sciencedirect.com/science/article/pii/S0303264712001700 View in LinkedIn

ENERGY STRATEGY. "Parthenogenesis is a fast way to consume a rich repository of free energy, e.g., an ample stock of food with a large number of individuals, whereas sexual reproduction is a fast way to consume diverse and dispersed resources with a large variety of individuals." (Parthenogenesis is a type of asexual reproduction in which the offspring develops from unfertilized eggs). http://www.sciencedirect.com/science/article/pii/S0303264712001700 View in LinkedIn

DIPLOID FORM. “For most plants and all animals, the majority of life is spent in diploid form. During sexual reproduction, haploid gametes are formed via meiosis and then come together during fertilization.  Some simpler Eukaryota spend most of their life cycle in diploid form.” https://lnkd.in/dTisCwg View in LinkedIn
