The extreme self-sacrificial behavior found in suicide bombers and soldiers presents an evolutionary puzzle: how can a trait that calls for an individual to make the ultimate sacrifice, especially in defense of a group of non-family members, persist over evolutionary time?

Sergey Gavrilets, a joint UT professor of math and ecology and evolutionary biology, was quoted in several articles about epigenetics.
Sergey Gavrilets recently spoke with WUOT 91.9 FM about human warfare and how it has evolved over time. Gavrilets, distinguished professor in the Department of Ecology and Evolutionary Biology, is one of the organizers of a three-day workshop that will explore warfare in human societies and how it has potentially acted as a source of natural selection for biological and cultural evolution.

Warfare not only hastened human technological progress and vast social and political changes, but may have greatly contributed to the evolutionary emergence of humans’ high intelligence and ability to work together toward common goals, according to a new study from the National Institute for Mathematical and Biological Synthesis.
A joint study from the National Institute for Mathematical and Biological Synthesis and the University of Oxford sheds new light on the evolutionary roots of group cooperation. Researchers say that leaders in group-living species may bully their own to get what they want, but they also bully outsiders for the overall betterment of their own group.
A study by Sergey Gavrilets, professor of ecology and evolutionary biology and associate director for scientific activities at National Institute for Mathematical and Biological Synthesis, has found that intense warfare is the evolutionary driver of large complex societies.
Sergey Gavrilets, professor of ecology and evolutionary biology, was quoted in a New York Times story about monogamy. The article is about a study which looked at 2,545 species of mammals, tracing their mating evolution from their common ancestor some 170 million years ago. The researchers found monogamy evolves when females become hostile with one

Is homosexuality genetic? It’s a long-running debate. Now researchers at UT say they’ve found a clue that may unlock the mystery. It lies in something called epi-genetics—how gene expression is regulated by temporary switches. A working group at NIMBioS used mathematical modeling that found the transmission of sex-specific epi-marks may signal homosexuality.
