Are animals altruistic? From eusocial animals like ants & bees, to well-documented cases of humpback whales rescuing seals from orcas, there are numerous examples of what looks like altruism in nature. Among many bird and mammal species, including meerkats, vervet monkeys, and jays, individuals give warning calls when a predator is nearby–an act that may save others, but temporarily puts the individual at greater risk of predation. In vampire bats, individuals routinely regurgitate blood to members of their colony who’ve had an unsuccessful night of feeding. From an evolutionary perspective, these behaviours are puzzling. Why would an animal regularly engage in activities that benefit others, at a cost to itself? Given that not all organisms act selfishly, is there a biological advantage to altruistic behaviour? How and why might it evolve?

London Public Library logoJoin us for an exploration of this fascinating topic at the 2020 Rotman Lecture, by Samir Okasha, at Wolf Performance Hall. This event is prepared in partnership with the London Public Library and is open to the public. Attendance will be free, but for planning purposes advance registration is requested. Can’t join us in person? This event will be live-streamed.

Registration for this event will be opened on 14 February 2020.

SPEAKER ABSTRACT


It is sometimes thought that Darwinian evolution implies that organisms will evolve to be “selfish”, that is, to behave in a way that furthers their own biological interests rather than those of others. However, biologists have long recognized that “altruistic” behaviour is quite common in nature, and have sought to reconcile this finding with evolutionary principles. This talk focuses on the philosophical implications of this classic biological issue, and asks how biologists use of terms such as “altruism” and “selfishness” relate to their vernacular use.

 

SPEAKER PROFILE


Samir OkashaSamir Okasha is a Professor in the Department of Philosophy at the University of Bristol. He is a Fellow of the British Academy, and President of the European Philosophy of Science Association. His philosophical interests fall into two main areas: (i) philosophy of biology / evolutionary theory; and (ii) epistemology /philosophy of science.

Within philosophy of biology, he is especially interested in foundational and conceptual questions surrounding evolutionary theory. For many years, his research focused on the ‘levels of selection’ question in evolutionary biology, and the related issue of individual versus group conflicts of interest. This culminated in his book Evolution and the Levels of Selection (OUP 2006), which was awarded the 2009 Lakatos Prize for an outstanding contribution to philosophy of science. He continues to work on these topics.

Within epistemology / philosophy of science, he is interested in topics including probability and induction, evidence and confirmation, causality, theory choice, scepticism and knowledge, and epistemological holism.
