Guenon Monkeys Cross Species Boundary
Leakey Foundation grantee Kate Detwiler from Florida Atlantic University is the first to document that two genetically distinct species of guenon monkeys inhabiting Gombe National Park in Tanzania, Africa, have been successfully mating and producing hybrid offspring for hundreds maybe even thousands of years.
Mapping Trees Can Help Count Endangered Lemurs
The vast majority of lemur species are on the edge of extinction, experts warn. But not every lemur species faces a grim future. A study funded in part by The Leakey Foundation has shown that there may be as many as 1.3 million white-fronted brown lemurs still in the wild, and mouse lemurs may number more than 2 million.
Seeing the World Through a Tarsier’s Eyes
Tarsiers are small (tennis ball-sized) nocturnal primates that have the largest eyes relative to body size of any known living or extinct vertebrate. Their enormous eyes are thought to enhance visually-guided predation by increasing visual sensitivity in dim light and contrasting an object of focus with a progressive depth of field.
Mother’s Milk Holds Key to Unlocking an Evolutionary Mystery From the Last Ice Age
As biologists explore the variation across the genomes of living people, they’ve found evidence of evolution at work. Particular variants of genes increase or decrease in populations through time. Sometimes this happens by chance. Other times these changes in frequency result from the gene’s helping or hindering individuals’ survival.
Neanderthal Mother, Denisovan Father
Together with their sister group the Neanderthals, Denisovans are the closest extinct relatives of currently living humans. Now researchers have discovered a tiny fossil from an individual who is the offspring of a Neanderthal mother and a Denisovan father.
