Professor Lee Berger, palaeontologist, explorer and member of The National Geographic Society, gestures as he explains the scientific relevance of discovering Homo Naledi in the Rising Star caves system in The Cradle of Human Kind, on May 11, 2023. The news shakes the foundations of human evolution: world-renowned paleontologist Lee Berger announced on Monday that he had discovered the oldest graves ever found in South Africa, pushing back the first traces of mortuary practices by some 100,000 years . The oldest tombs discovered so far were found in Israel and Egypt at the beginning of the 20th century. They date from around 100,000 years before our era and house the remains of Homo sapiens, the direct ancestor of man. The burials unearthed in South Africa date from -200,000 to -300,000 years.

Cave of Bones review: Lee Berger on the discovery of Homo naledi

The newly discovered Perucetus colossus, an ancient species of whale, is thought to be one of the largest and heaviest animals on record, reports a study published in Nature. Estimates of its size and weight, based on a partial skeleton, rival those of the blue whale, which was previously thought to be the heaviest animal ever to exist. The findings suggest that the trend towards gigantism in marine mammals may have begun earlier than previously thought. Reconstruction of Perucetus colossus in its coastal habitat.
