sapiens teeth, including remains of predatory cats, have previously been dated at other sites to no more than around 120,000 years ago
If sea levels only 120,000 years ago
were about the same as they are now, then the global ratio of ice-to-water was probably similar to what it is today.
The researchers found that approximately 120,000 years ago
, the sea came close to drying up entirely, with another period of extreme dryness taking place about 13,000 years ago.
It is known that some 120,000 years ago
- a mere tremor in the eyelid of time - the mean temperature of the world was five degrees warmer than it is now.
Instead of stable sea levels, the researchers estimated that the sea level oscillated up and down by 4 to 6 metres (13 to 20 feet) over a few thousand years, approximately 120,000 years ago
during a period of time known as the Last Interglacial.
Because this warm period happened relatively recently, about 120,000 years ago
, scientists could independently determine its sea level.
This way, we were able to estimate that the crossing of the Andes occurred more than 120,000 years ago
," she added.
The Australian rains were strongest during the last warm interglacial period, about 120,000 years ago
In modern humans starting 120,000 years ago
, compassion was extended to strangers, animals, objects and abstract concepts.
According to the new study, the last interglacial began sometime before 127,000 years ago and ended 120,000 years ago
, the scientists report in the Sept.
The two researchers suggest that a greenhouse warming may bring the same sort of conditions that stimulated the growth of glacial sheets 120,000 years ago
In 2007, Frohlich studied these boulders, which have dimensions as large as 9 meters and weigh up to 1600 tons, and concluded that the boulders originated at the shoreline about 120,000 years ago
and have since been displaced by a prehistoric tsunami.
