Roosters, famously, crow in the early morn -- but scientists don't fully understand why they unleash their voices when they do. After all, roosters have also been known to make a racket when other animals or birds are about, when a car starts, or when lights turn on in the middle of the night. So do they crow because they see the morning light, or because they hear other roosters? Or do they have some kind of internal body clock that lets them know that's it's time to unleash their peals?

Today, a century and a half after Charles Darwin published "On the Origin of Species by Means of Natural Selection," the overwhelming majority of scientists in the United States accept Darwinian evolution as the basis for understanding how life on Earth developed. But although evolutionary theory is often portrayed as antithetical to religion, it has not destroyed the religious faith of the scientific community. According to a survey of members of the American Assn. for the Advancement of Science, conducted by the Pew Research Center in May and June this year, a majority of scientists (51%)

SEATTLE - The long-running detective saga involving one of North America's earliest inhabitants has taken a new twist, with news that Kennewick Man - the shockingly intact 9,300-year-old skeleton unearthed in 1996 on the banks of the Columbia River - probably was a visitor to central Washington, not a longtime inhabitant. More likely, Smithsonian Institution anthropologist Douglas Owsley announced in a pair of lectures this week in Washington state, he came from the coast, not the arid inland valley where his remains were found.

Whether it's the vaccination that protects us from polio or the telephone that lets us talk with the neighbor down the street or around the world, our lives are enriched by the work of scientists. But what motivates people to study how and why things work, to dream up inventions that save lives or enable space travel? And why is it important to study galaxies or to view the activities of a single cell?

To many, human-animal chimeras--animals that contain human cells--sound like the stuff of nightmares. If you can picture a frog with a human head, a monkey with human vocal chords or a dog with opposable thumbs, you can see why some people want to put the brakes on any sort of scientific experiment that mixes cells from different species. The reality of chimeras is much less dramatic: Picture instead a pig that produces human insulin or a mouse getting chemotherapy for its human cancer cells.

UC San Diego graduate student Alex Piel is studying the family dynamics and habitats of chimpanzees in Tanzania's savanna. The research requires tracking animals, retrieving fecal samples and then testing to confirm genetic links. It does not come cheap. So after tapping traditional funding help from UC and other sources, Piel and Fiona Stewart, his wife and collaborator, recently decided to try their luck on the Internet. They posted a description of their project and an appeal to the public for money on Experiment , an online crowdfunding site devoted to science.
