If so, Darwin suggested, they probably also have an adaptive Typically, an adaptation is an evolved modification that a species develops in order to better survive in different environments. Adaptations can be divided into two Sep 1, 2009 Principles of Evolution, Ecology and Behavior (EEB 122)Adaptive Evolution is driven by natural selection. Natural selection is not "survival of Feb 2, 2010 Adaptive problems are diverse, and depend exquisitely on the life history of the species in question. That is, because different organisms survive Jul 22, 2010 Are constraint hypotheses genuine rivals to adaptive hypotheses? 6.

Evolutionarily adaptive

The population can be assumed to be at equilibrium when a new mutant ari When a condition or situation of an evolutionarily recognizable kind is detected, a signal is sent out from the emotion program that activates the specific constellation of subprograms appropriate to solving the type of adaptive problems that were regularly embedded in that situation, and deactivates programs whose operation might interfere with solving those types of adaptive problem. But remember that this word means a very different thing in evolutionary terms than it does when used in clinical settings. Because natural selection operates only on phenotypes, not human values, Ethology is the scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. As long as only 3% of population is sociopathic, sociopathy may in fact be evolutionarily adaptive. And this may have been truer in the past -- before there were police with modern technology, and before birth control -- than it is now. Sociopaths make great first impressions. They are exciting, dynamic, charming, even electrifying.

Knowledge about tumour evolutionary dynamics has been growing rapidly. However, there has been a limited translation of that knowledge into therapeutic trials. The most clinically advanced strategy is adaptive therapy. Adaptive therapy is a treatment strategy attempting to prolong response to treatment by delaying the emergence of resistance.

evolutionarily exploited Adaptive radiation: evolutionary divergence of members of a single phylogenetic lineage into a variety of different adaptive forms (Futuyma 1998) Diversiﬁcation: the evolution of phenotypically and reproductively distinct species in a clade Key innovation: the evolution of a trait that allows a species to interact with the In 1963, Ernst Mayr, one of the founders of modern Evolutionary Biology defined a novelty as a new structure or property of an organism that allows it to perform a new function, thus opening a new "adaptive zone". In this reckoning, a novelty allows an organism to exploit a new ecological resource and should lead to an adaptive radiation 1. Is Suicide a Tragic Variant of an Evolutionarily Adaptive Set of Behaviors?

Translation for 'evolutionary' in the free English-Swedish dictionary and many other devil cancer has acquired an absolutely amazing evolutionary adaptation.

Adaptive problems are evolutionarily long-enduring recurring clusters of conditions that constitute either reproductive opportunities (e.g., the arrival of a potential mate; the reflectant properties of light) or reproductive obstacles (e.g., the speed of a prey animal; the actions of a sexual rival, limited food supplies for relatives). Adaptations were designed by selection to exploit these opportunities and to circumvent these obstacles. Abstract We present a general framework for modelling adaptive trait dynamics in which we integrate various concepts and techniques from modern ESS-theory. The concept of evolutionarily singular strategies is introduced as a generalization of the ESS-concept. As long as only 3% of population is sociopathic, sociopathy may in fact be evolutionarily adaptive.
