One of the greatest mysteries in science is why there is only one species of humans in the world today. In the past, there were several and they often co-existed for considerable periods. These past human species are modern humans older ancestors. Now, researchers believe that they know why our ancestors disappeared. Since they could not adapt to climate change the past human species became extinct, unlike Homo sapiens .

Underwater coral skyscraper taller than the Empire State Building found in Great Barrier Reef – Telegraph.co.uk
The reef was explored by underwater robot SuBastian, which livestreamed its discoveries
An underwater coral skyscraper taller than the Empire State Building has been discovered in the Great Barrier Reef.
Scientists from Australia’s James Cook University said they were “surprised and elated” to find the 1,640ft structure, the first detached coral reef to be discovered in 120 years.
The team aboard the Schmidt Ocean Institute’s Falkor ship made the discovery last week as part of efforts to map the reef sea floor.
On Monday the Institute, a non-profit founded by former Google chief executive…
Water exists on the moon, scientists confirm – The Guardian
Proof of significant amounts of H2O has implications for future lunar missions
Scientists have gathered some of the most compelling evidence yet for the existence of water on the moon and it may be relatively accessible. The discovery has implications for future missions to the moon and deeper space exploration.
With no significant atmosphere insulating it from the suns rays, it had been assumed that the moons surface was dry until the 1990s, when orbiting spacecraft found indications of ice in large and inaccessible craters near the moons poles.
Then in 2009, imaging spectrometers…
