Sweating made us the dominant species on the planet

NewImageOne theory of human evolution states that our ancestors began eating meat about 2 million years ago, whose caloric and fat density allowed the enlargement and development of their brains.

Hominids didn’t begin using stones and sticks for hunting until about 200,000 years ago. So between 2.3 million and 200,000 years ago, our original strategy was to run game animals to death in order to feast upon them. Sweating was the key factor in the ability to run long distances to wear out quarry without overheating. Game animals, who cannot sweat, become overheated over time and are at risk of damaging themselves or dying if they don’t stop to catch their breath, allowing early hunters to catch and dispatch them. Animals that do not walk upright cannot fully extend their diaphragms to take deep breaths until they stop running.

Some tribal peoples still take part in persistence hunting and there is evidence that the strategy was utilized all over the world in the distant past. This helps us to understand why several aspects of human development — walking upright, hairless skin, sweating, and the ability to run long distances — appear to have evolved simultaneously.

Will cows inherit the planet after humans die out?

NewImageWhen humans die out because of climate change, they may be the biggest and most widespread animal left, thereby inheriting the planet. 

‘After humans started migrating out of Africa, the largest land mammals have died out in each territory that humans have spread to. It’s somewhat of a human hallmark, making other species extinct, although we’ve kept cows around for both food and leather. We’ve actually prioritized cows over other species, leading to a 1.5 billion total cow population across the globe. That’s more than cats and dogs combined: there are only 500 to 600 million dogs in the world and about as many cats.

If global warming keeps going at its current pace, Stephen Hawking estimated last year that humanity has about 100 years left to find a new planet to live on and only 1,000 years left on this planet before the heat completely kills all life. Pre human-kind meddling, larger animals simply adapted to climate change. But at this accelerated pace, species go extinct at an astronomical level. Between 24-100 species every day become extinct, and that’s a conservative estimate. Because there are so many cows on the planet, it’s fairly safe to say that even if all humans died out tomorrow all cows would have to do is graze and slowly move north as the planet got hotter. That’s conjecture, sure, but from a strictly numerical standpoint, there’s a good chance that cows will enjoy a very short time at the top of the food chain before the planet becomes completely uninhabitable except for cockroaches….’

A Short History of Threats Received by Donald Trump’s Adversaries

Decca Muldowney writes:

‘When Stormy Daniels spoke to “60 Minutes” last month, the porn actress described a threat she received years ago after speaking to a journalist about her alleged affair with Donald Trump. A stranger approached her in a parking lot in Las Vegas. Daniels was there with her baby daughter. “Leave Trump alone,” Daniels recalled the man warning her. “That’s a beautiful little girl. It’d be a shame if something happened to her mom.”

Daniels did not report the threat to the police. On Wednesday, Donald Trump tweeted that Daniels’ account of events was “a total con job” about a “non-existent man.”

As it happens, other people in disputes with Trump have also found themselves the targets of threats — and sometimes they’ve reported it to authorities. …’
