Years from now Event 1,000 Due to the lunar tides decelerating the Earth's rotation, the average length of a solar day will be 1 ⁄ 30 of an SI second longer than it is today. To compensate, either a leap second will have to be added to the end of a day multiple times during each month, or one or more consecutive leap seconds will have to be ...
In 10,000 years, the post-glacial rebound of the Baltic Sea will have reduced the depth by about 90 m (300 ft). The Hudson Bay will decrease in depth by 100 m over the same period. [38] After 100,000 years, the island of Hawaii will have shifted about 9 km (5.6 mi) to the northwest. The planet may be entering another glacial period by this time.
Accelerated divergence due to selection pressures in populations participating in the Neolithic Revolution after 12 ka, e.g. East Asian types of ADH1B associated with rice domestication, [74] or lactase persistence. [75] [76] A slight decrease in brain size occurred a few thousand years ago. [citation needed]
In the human-infested ecosystem, those preadapted to live amongst man survived and prospered. Ward describes garbage dumps 10 million years in the future infested with multiple species of rats, a snake with a sticky frog-like tongue to snap up rodents, and pigs with snouts specialized for rooting through garbage. The story's time traveller who ...
See Hawking through the years: He has, in the past, noted , "I believe that life on Earth is at an ever-increasing risk of being wiped out by a disaster, such as a sudden nuclear war, a ...
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
If humans living for 1,000 years seems like a complete stretch, aging expert João Pedro de Magalhães will do you one better: how about humans living for 20,000 years?. The professor of molecular ...
For 28 modern human specimens from 190 to 25 thousand years ago, average brain volume was estimated to have been about 1,478 cc (90.2 cu in), and for 13 Cro-Magnons about 1,514 cc (92.4 cu in). In comparison, present-day humans average 1,350 cc (82 cu in), which is notably smaller.
