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.

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.
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.
Discovered more than half a century ago in Kenya and sitting in museum storage ever since, the roughly 20-million-year-old fossil Propotto leakeyi was long classified as a fruit bat. Now, it's helping researchers rethink the early evolution of lemurs, distant primate cousins of humans that today are only found on the island of Madagascar, some 250 miles off the eastern coast of Africa.
An international team, including Leakey Foundation grantees and researchers at Stony Brook University and the Max Planck Institute for the Science of Human History, has found the earliest and largest monumental cemetery in eastern Africa.
