Weighing around 300 pounds, the loggerhead sea turtle is one of the world’s largest hard-shelled turtle. The maximum reported weight of an loggerhead is 1,202 lb

While loggerheads can be found across Pacific, Atlantic, Mediterranean and Indian Oceans, persistent population has declined due to continuous pollution, shrimp trawling and development in their nesting areas. They are now on the threatened species list.

In the southeastern United States loggerhead mating occurs in late March till early June and females lay eggs between April and September. The major nesting concentration in the U.S. are found from North Carolina through southwest Florida.

More than 50 million people live in the remote parts of the Himalayas and their very existence is dependent on the mountains and its resources.

But exactly how these mountain dwellers survive in the high-altitude and the ease with which they deal with the physical challenges of scaling world’s biggest peaks has remained unknown.

But there are some clues. According to a research published in the American Journal of Human Genetics, these mountain dwellers have a major genetic component that allows populations at high altitude to live better. The scientists are still unclear exactly how those genes work and help people survive in low-oxygen condition, but they also believe that there are probably other mutations that also help and different populations for example people in the highlands of Ethiopia.
