As you can tell, I spend my Sunday Mornings reading the major newspapers and news outlets on line.  I learn so much…

Here is yet another fascinating article from NPR:

Our earliest ancestors ate their food raw — fruit, leaves, maybe some nuts. When they ventured down onto land, they added things like underground tubers, roots and berries.

It wasn’t a very high-calorie diet, so to get the energy you needed, you had to eat a lot and have a big gut to digest it all. But having a big gut has its drawbacks.

“You can’t have a large brain and big guts at the same time,” explains Leslie Aiello, an anthropologist and director of the Wenner-Gren Foundation in New York City, which funds research on evolution. Digestion, she says, was the energy-hog of our primate ancestor’s body. The brain was the poor stepsister who got the leftovers.

Until, that is, we discovered meat.

“What we think is that this dietary change around 2.3 million years ago was one of the major significant factors in the evolution of our own species,” Aiello says.

As we got more, our guts shrank because we didn’t need a giant vegetable processor any more. Our bodies could spend more energy on other things like building a bigger brain. Sorry, vegetarians, but eating meat apparently made our ancestors smarter — smart enough to make better tools, which in turn led to other changes, says Aiello…..

Our teeth, jaws and mouth changed as well as our gut.

and one more excerpt:

It’s not as if raw food isn’t nutritious; it’s just harder for the body to get at the nutrition.

Wrangham urges me to try some raw turnip. Not too bad, but hardly enough to get the juices flowing. “They’ve got a tremendous amount of caloric energy in them,” he says. “The problem is that it’s in the form of starch, which unless you cook it, does not give you very much.”

Then there’s all the chewing that raw food requires. Chimps, for example, sometimes chew for six hours a day. That actually consumes a lot of energy.

“Plato said if we were regular animals, you know, we wouldn’t have time to write poetry,” Wrangham jokes. “You know, he was right.”

Fascinating article in today’s Washington Post about the different generations and texting vs calling.

Maybe I’m younger than I think as I hate to talk on the phone but love to text!

Here is an excerpt and the usual link to the full post at the bottom:

Jane Beard and Jeffrey Davis didn’t realize how little they speak to their children by phone until they called AT&T to switch plans. The customer service agent was breathless. The Silver Spring couple had accumulated 28,700 unused minutes.

“None of the kids call us back! They will not call you back,” said Beard, a former actress who with her husband coaches business leaders on public speaking.

A generation of e-mailing, followed by an explosion in texting, has pushed the telephone conversation into serious decline, creating new tensions between baby boomers and millennials — those in their teens, 20s and early 30s.

Nearly all age groups are spending less time talking on the phone; boomers in their mid-50s and early 60s are the only ones still yakking as they did when Ma Bell was America’s communications queen. But the fall of the call is driven by 18- to 34-year-olds, whose average monthly voice minutes have plunged from about 1,200 to 900 in the past two years, according to research by Nielsen. Texting among 18- to 24-year-olds has more than doubled in the same period, from an average of 600 messages a month two years ago to more than 1,400 texts a month, according to Nielsen.

Young people say they avoid voice calls because the immediacy of a phone call strips them of the control that they have over the arguably less-intimate pleasures of texting, e-mailing, Facebooking or tweeting. They even complain that phone calls are by their nature impolite, more of an interruption than the blip of an arriving text.

Kevin Loker, 20, a rising junior at George Mason University, said he and his school friends rarely just call someone, for fear of being seen as rude or intrusive. First, they text to make an appointment to talk. “They’ll write, ‘Can I call you at such-and-such time?’ ” said Loker, executive editor of Connect2Mason.com, a student media site. “People want to be polite. I feel like, in general, people my age are not as quick on their feet to just talk on the phone.”
