160,000 years ago, Homo sapiens idaltu in the Awash River Valley (near present-day Herto village, Ethiopia) practiced excarnation. [59] 130–80 ka Marine Isotope Stage 5 . Modern human presence in Southern Africa and West Africa. [60] Appearance of mitochondrial haplogroup (mt-haplogroup) L2. 80–50 ka MIS 4, beginning of the Upper Paleolithic.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
The following is a list of centenarians – specifically, people who became famous as authors, editors, poets and journalists – known for reasons other than their longevity. For more lists, see lists of centenarians.

The researchers looked at 181 potential risk factors, and then estimated how likely they are to predict dementia and cognitive impairment for people two, four, and 20 years after they turn 60.
The real and lasting effects of ageism. The global life expectancy was 71.4 years in 2021, but healthy life expectancy in older age is more than the absence of disease. Things that impact healthy ...
Reconstruction of early Homo sapiens from Jebel Irhoud, Morocco c. 315 000 years BP. Early modern human (EMH), or anatomically modern human (AMH), [1] are terms used to distinguish Homo sapiens (sometimes Homo sapiens sapiens) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species (of which some are at times also identified ...
