Amotz Zahavi (Hebrew: אמוץ זהבי) (August 14, 1928[1] – May 12, 2017) was an Israeli evolutionary biologist, a Professor in the Department of Zoology at Tel Aviv University, and one of the founders of the Society for the Protection of Nature in Israel. His main work concerned the evolution of signals, particularly those signals that are indicative of fitness, and their selection for "honesty".

Biography

Amotz Zahavi was influenced to study zoology by the director of the zoo at Tel Aviv, Heinrich Mendelssohn.

Ph.D. from Tel Aviv University in 1970. He was married to Avishag Zahavi, a biologist and a co-investigator. He died in Tel Aviv, Israel on May 12, 2017, aged 88.[2]

Main articles: Handicap principle and Signalling theory

Zahavi is best known for his work on the

altruistic behaviour among unrelated individuals, not explainable by kin selection. Zahavi reinterpreted these behaviours according to his signal theory and its correlative, the handicap principle. The altruistic act is costly to the donor, but may improve attractiveness to potential mates, a form of competitive altruism.[4][5][6]

Zahavi is credited with co-developing the information centre hypothesis in 1973 with Peter Ward.[7] The information centre hypothesis states that birds live in communal roosts primarily to gain information on food resource locations from other roost individuals.[7]

Towards the end of his life he attempted to apply his theory at the molecular scale and sought to examine for example whether the neurotransmitter acetylcholine was selected due to its toxicity.[8]

Awards

In 1980, The Society for the Protection of Nature in Israel, Zahavi and two other colleagues, were awarded the Israel Prize for SPNI's special contribution to society and the State, for the environment.[9]

In 2011, Zahavi received the

Fyssen Foundation's International Prize for the evolution of social communication.[10]

In 2016, Zahavi received a prize for lifetime achievement from the Israel Society of Ecology and Environmental Sciences.[11]
