Are Some Human Gene Sets More Adapted For Thermal Stress and Greater Extremes?

Species must adapt to their environment or they become former species, extinct. They either adapt or die even if the changes are abrupt they must cope, reproduce, and survive or else. Guess what? Humans are no different in this regard. Whereas, humans can modify their environment - heating, air-conditioning, etc. they still have to deal with the outside conditions, unless they wish to go live in caves in the future, or underground. Of course, then they must adapt to those new conditions, you see the point?

One of the biggest issues is thermal or heat stress. In fact, in the Journal of Ergonomics (volume 16, issue 5, 1973) there was an interesting paper titled; "Thermal Stress and Thermal Comfort" by RK MacPherson with an abstract which stated;

New Dinosaur Extinction Theory - Blame the Deccan Trappes

New Study Points Finger at Deccan Traps for Extinction Event

In 1980, American scientists Luis and Walter Alvarez published their theory regarding an extra-terrestrial body impacting with the Earth, causing the mass extinction event that marked the end of the Age of Reptiles. The discovery of the Chicxulub crater in the Gulf of Mexico, the "smoking gun" evidence in the 1990's added credence to this theory put forward by the father and son team.

Recent studies of the asteroid belt that lies between Mars and the outer planets had led one group of scientists to deduce the fate of the dinosaurs was sealed back in the Jurassic when an impact between huge asteroids sent one immense lump of space rock on a collision course with Earth.

Important Australian Dinosaur Fossil Site Threatened by Developers

Rare Australian Dinosaur Fossils Threatened Desalination Plant

One of the widely publicised impacts of global warming and climate change has been the very severe drought suffered by much of Australia in the last couple of years. Many scientists claim that global climate change was one of the causal factors in the extinction of the dinosaurs 65 million years ago and now climate change is indirectly threatening the excavation of rare dinosaur fossils down under.

Desalination Plant to be Built on Dig Site

In East Gippsland, south-east Victoria, the demands for drinking water have grown rapidly as the population increases.

More Prehistoric Turtle Remains From a Columbian Coal Mine

Giant Turtle with a Rounded Shell - Reptiles Ruled When Dinosaurs Died Out

Palaeontologists and field workers have been marvelling at the latest discovery of huge reptile fossils from Columbia's Cerrejon coal mine. After the dinosaurs died out, there were many gaps in ecosystems, these were rapidly filled by animals that had survived the Cretaceous mass extinction event that saw the demise of the Dinosauria. In the geological time period that followed the Cretaceous, known as the Palaeogene, global temperatures soared and planet Earth became a paradise for those reptile genera that survived.

Sixty Million Year Old Giant Turtle

The research team have uncovered the carapace of another enormous freshwater turtle from the coal mine.
