Scientists discover oldest evidence of split between Old World monkeys and apes
ATHENS, Ohio (May 15, 2013) — Two fossil discoveries from the East African Rift reveal new information about the evolution of primates, according to a study published online in Nature today led by Ohio University scientists. The team’s findings document the oldest fossils of two major groups of primates: the group that today includes apes and humans (hominoids), and the
Studying Hormonal Stimuli in Mountain Gorillas Yields Many Clues
By Sosthene Habumuremyi
My study has gathered data on mating behavior, solicitations, and any displays/aggression from adult males towards the females. Sexual swellings, which are extremely small in gorillas, are also noted.
The plan is to monitor at least 6 nulliparous (never having given birth to offspring) females and 10 cycling parous (given birth to offspring at least once) females
The hormonal correlations of socio-sexual behaviors in female mountain gorillas
By Sosthene Habumuremyi The overall goal of this study is to investigate the hormonal correlates of socio-sexual behaviors in female mountain gorillas. Specifically, we want to understand the variation observed in mating strategies and fertility parameters among female mountain gorillas. By using hormonal data, we want to know if this variation is governed by internal stimuli. For a detailed analysis,
Wonderfest 2010: How Did Evolution Shape Human Behavior?
In November, Stanford University and UC Berkeley were home to the 12th Annual Bay Area Festival of Science, aptly named Wonderfest. Two Leakey Foundation Grantees, Henry Gilbert, Assistant Professor of Anthropology at CSU East Bay and David DeGusta, former Assistant Professor of Anthropology at Stanford, were featured speakers. They jointly discussed how evolution has shaped our behavior today.
