The Rise of Culture and the Fall of Testosterone

Behind the Science, Education
In a paper published in the journal Current Anthropology, a team of researchers funded by The Leakey Foundation explore the biological basis of the technology boom and expansion of culture that happened 50,000 years ago. DURHAM, N.C. — Modern humans appear in the fossil record about 200,000 years ago, but it was only about 50,000 years ago that making art and advanced tools became widespread. A newmore »

Behind the Science, Guest Post, Education
by Dr. Anne Stone,  Arizona State University Photo: David Bygott BY-NC-SA 2.0 How hard can it be to extract DNA from the teeth of chimpanzees that died only 30 or 40 years ago? These were my initial thoughts when presented with the opportunity to examine the DNA of the most famous chimpanzees in the world. These individuals, studied by Dr. Jane Goodall at Gombe, included Flo, Madam Bee, Satan, Hugo, and Getty.more »

Studying Hormonal Stimuli in Mountain Gorillas Yields Many Clues

Grantee Spotlight, From the Field, Behind the Science, Guest Post, Education
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 for 2 cycles more »

The hormonal correlations of socio-sexual behaviors in female mountain gorillas

Education

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,more »
