MONTAGNE: But the gray wolf is the ancestor of all domesticated dogs, including that Jack Russell terrier we just heard. Just how wolves came to live with people isn't really known. But as NPR's Veronique LaCapra reports, a new study suggests that food may have played a role.
VERONIQUE LACAPRA, BYLINE: Most dogs will eat just about anything.
The National Institutes of Health should retire most of its chimps that are currently living in research facilities, according to a working group put together by the NIH to look at the future need for biomedical research on chimps.
The group did recommend keeping a small number of chimps in reserve in case they are needed for studies later on. But it also laid out a detailed description of the kind of living conditions that would be needed for those chimps, and said any proposed research should go through a review committee that includes members of the public.
