The oldest-known male captive chimpanzee to have been documented lived to 66 years, [74] and the oldest female, Little Mama, was nearly 80 years old. [75] Leopards prey on chimpanzees in some areas. [76] [77] It is possible that much of the mortality caused by leopards can be attributed to individuals that have specialised in killing ...
Different chromosomes appear to have split at different times, possibly over as much as a 4-million-year period, indicating a long and drawn out speciation process with large-scale gene flow events between the two emerging lineages as recently as 6.3 to 5.4 million years ago, according to Patterson et al. (2006). [21]
The Atlantic is estimated to have been possibly 1,000 km (600 mi) narrower, based on estimates from the expansion of the Atlantic mid-ocean ridge formation processes (25 cm/1 in per year.) It is also possible that during this rafting process, there were a number of islands between Africa and South America which have since been submerged.
Hominini: The latest common ancestor of humans and chimpanzees is estimated to have lived between roughly 10 to 5 million years ago. Both chimpanzees and humans have a larynx that repositions during the first two years of life to a spot between the pharynx and the lungs, indicating that the common ancestors have this feature, a precondition for ...
It has been argued that human evolution has accelerated since the development of agriculture 10,000 years ago and civilization some 5,000 years ago, resulting, it is claimed, in substantial genetic differences between different current human populations, [210] and more recent research indicates that for some traits, the developments and ...

At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
It’s been just over two years since Tonka arrived at Save the Chimps, a 150-acre parcel of protected land where 222 apes born in captivity have come to live out their retirement.
