Many children's books and songs double as mini-lessons in counting (One Elephant), letters (the alphabet song) or fine-motor skills (Thumbkin). It's less common to find such activities for young children infused with basic science.

Take evolution. Perhaps it hasn't made it into classic nursery rhymes because it's all about sex and death — not the easiest topics to discuss with little folks. It's also challenging for adults to understand and accept, in part because a solid understanding of evolution rests on some pretty sophisticated concepts, including deep time and probability.

So I have great admiration for recent efforts to make evolution more accessible to young, inquiring minds. Grandmother Fish, for example, is a Kickstarter campaign (on track to be funded next week) that aims to produce "a child's first book of evolution," with a focus on communicating the idea of common descent. Great Adaptations is a book targeting older children, with contributions from a variety of scientists and illustrators showcasing biological adaptations.

But as far as I can tell, the burning need for a nursery rhyme about natural selection remains to be met. And I'm here to rise to the challenge. I offer — only half in jest — alternative lyrics to the classic Five Little Monkeys, fully uncensored, sex-and-death style. Thanks to two co-conspirators, Elizabeth Bonawitz and Tom Griffiths, you can appreciate it in full audiovisual grandeur:

WASHINGTON (AP) — Two key lawmakers say President Barack Obama can alleviate a growing humanitarian crisis involving tens of thousands of child immigrants without waiting for Congress to act.

Democratic Sen. Dianne Feinstein of California and Republican Rep. Mike Rogers of Michigan both say Obama does not need to wait for changes in a 2008 human trafficking law before ordering the return of some children to their native countries.

The law requires immigration judges to decide the fate of young border crossers from countries that don't border the United States. The Obama administration has expressed some interest in changing the law.

Feinstein wrote the legislation at issue, while Rogers is chairman of the House Intelligence Committee.

More than 57,000 children, mostly from Central America, have crossed the border with Mexico since Oct. 1.

President Obama has sent Congress an almost $4 billion request to deal with the situation at the southern border, where children from Central America continue to arrive. The president has said it's a stopgap measure — that what's really needed is an immigration overhaul. But Republicans argue they can't trust Obama, as they point to other instances of laws they say he has ignored.

ENTIAT, Wash. (AP) — A wildfire burning on about 34 square miles of grass, brush and timber in central Washington did not grow on Saturday, but officials worry that storms forecast to arrive Sunday evening could cause explosive growth.

The Mills Canyon Fire, burning near Entiat (EHN'-tee-aht), was 25 percent contained on Sunday, said spokesman Vladimir Steblina of the Pacific Northwest Incident Management Team.

Residents of several dozen homes have been told to evacuate. People living in another 500 homes have been warned to be prepared to leave, if the fire gets closer.

The National Weather Service says thunderstorms with dry lightning were expected in the area around 8 p.m.

"When the winds start swirling around, you get really erratic winds," Steblina said. "We might end up with extreme fire growth around the thunder cells."

About 781 firefighters, assisted by eight helicopters were battling the fire on Sunday, concentrating on the north and south lines.

"The day has gone as planned," said fire spokeswoman Laurie Dowie on Sunday afternoon. Fire lines on both the south and north ends of the fire were strengthened.

No people have been injured in the fire, but three small sheds or outbuildings have been burned, Steblina said.

In addition to the blaze, firefighters are battling extreme heat. The high in nearby Wenatchee reached 106 degrees on Saturday. Fire officials were expecting temperatures above 90 again on Sunday.

"People are paying a lot of attention to being hydrated," Steblina said, noting that the only medical issues on the fire have been a few cases of poison ivy.
