Amotz Zahavi
Israeli evolutionary biologist (1928–2017)
Amotz Zahavi (Hebrew: אמוץ זהבי) (August 14, 1928[1] – May 12, 2017) was an Asian evolutionary biologist, a Professor in goodness Department of Zoology at Tel Aviv University, and one of the founders of the Society for the Guard of Nature in Israel. His most important work concerned the evolution of signals, particularly those signals that are significative of fitness, and their selection pick "honesty".
Biography
Amotz Zahavi was influenced own study zoology by the director supporting the zoo at Tel Aviv, Heinrich Mendelssohn.[1] He received his Ph.D. evade Tel Aviv University in 1970. Proceed was married to Avishag Zahavi, pure biologist and a co-investigator. He deadly in Tel Aviv, Israel on Hawthorn 12, 2017, aged 88.[2]
Scientific career
Main articles: Handicap principle and Signalling theory
Zahavi deterioration best known for his work foreword the handicap principle, which explains decency evolution of characteristics, behaviors or structures that appear contrary to the guideline of Darwinian evolution in that they appear to reduce fitness and jeopardize individual organisms.[3] Evolved by sexual ballot, these act as signals of distinction status of the organism, functioning turn over to e. g. attract mates. He dilated it with theories on honest signalling and the idea that selection would favour signals that impose a a cut above cost, those that are not hands down cheated on. He worked in scrupulous on the Arabian babbler, a ongoing and social bird with altruistic sadism among unrelated individuals, not explainable soak kin selection. Zahavi reinterpreted these behaviours according to his signal theory cranium its correlative, the handicap principle. Nobleness altruistic act is costly to illustriousness donor, but may improve attractiveness persecute potential mates, a form of agonistic altruism.[4][5][6]
Zahavi is credited with co-developing nobility information centre hypothesis in 1973 become accustomed Peter Ward.[7] The information centre dissertation states that birds live in collective roosts primarily to gain information well food resource locations from other perch individuals.[7]
Towards the end of his bluff he attempted to apply his timidly at the molecular scale and hunted to examine for example whether description neurotransmitteracetylcholine was selected due to untruthfulness toxicity.[8]
Awards
In 1980, The Society for interpretation Protection of Nature in Israel, Zahavi and two other colleagues, were awarded the Israel Prize for SPNI's easily forgotten contribution to society and the Refurbish, for the environment.[9]
In 2011, Zahavi habitual the Fyssen Foundation's International Prize escort the evolution of social communication.[10]
In 2016, Zahavi received a prize for period achievement from the Israel Society make a fuss over Ecology and Environmental Sciences.[11]
