Fewer than 10 percent of all mammal species are monogamous. In fact, biologists have long disagreed over why monogamy exists at all. That's the subject of two studies published this week — and they come to different conclusions.
Animals that leave the most offspring win the race to spread their genes and to perpetuate their lineage. So for most mammals, males have a simple strategy: Mate with as many females as possible.
"Monogamy is a problem," says Dieter Lukas, a biologist at Cambridge University. "Why should a male keep to one female?"
Good morning. I'm David Greene. Russian President Vladimir Putin is known for getting out and experiencing the great outdoors. All of his pursuits are meticulously documented by the media. He's ridden horseback shirtless, tranquilized a tiger, plunged into a lake in a submarine, and led migrating birds in a motorized glider.
In Texas, ThelmaandLouise is a big draw - not the movie. ThelmaandLouise, one word, is the name of a two-headed turtle born at the San Antonio Zoo last month. The Texas cooter is so popular, she has her own Facebook page and more than 1,700 friends. Her page says she - or they - is interested in meeting Maryland Terrapins and sea turtles. Double dating?

A new show on ABC Family follows a family with one biological kid, two adopted kids and a new addition, a teenage foster kid.

It is the toughest unit in the toughest prison in California and one of the toughest in the country. The security housing unit at Pelican Bay prison is home to convicts who, along with their largely violent crimes, are suspected of being part of California's ruthless prison gangs, gangs that hurt and kill in prison and control all kinds of illegal activity inside.
The largest solar power plant of its kind is about to turn on in California's Mojave Desert.
The Ivanpah Solar Electric Generating System will power about 140,000 homes and will be a boon to the state's renewable energy goals, but it was no slam dunk. Now, California is trying to bring conservationists and energy companies together to create a smoother path for future projects.
Some of Miami Beach's quietest and most historic neighborhoods can be found in a chain of small islands connected by a causeway. On Di Lido Island, a community of homes built 50 and 60 years ago is being torn down and replaced, lot by lot. On one street alone, five houses currently are slated for demolition.
Daniel Ciraldo stands across the street from two '60s-era houses that will soon be demolished and replaced by a new home nearly double their combined size.
Good morning. I'm David Greene. What better way to beat the summer heat than jumping in a pool? That's what some guys in Germany did, but their pool was a converted an open-top BMW - complete with tiki decorations - still drivable. The fun, though, dried up when they passed a motorcycle cop. They pulled over, abandoned the vehicle and jumped into a nearby river. The investigation is still ongoing, but the police did say this car pool probably didn't have a road permit.
