In the hope of reconstructing a pivotal step in evolution researchers have decoded the genome of the coelacanth, a prehistoric-looking fish whose form closely resembles those seen in the fossils of 400 million years ago.

Scientists studying the evolution of speech have long puzzled over why there are no good models in primates. While primates share many traits with humans — they’ve been known to play, grieve, fight, even laugh – speech isn’t one of them.

The goal of a scientist was to bring the extinct gastric brooding frog back from oblivion and, in doing so, provide hope for the hundreds of other frogs that are heading that way.

As the number of species at risk of extinction soars, zoos are increasingly being called upon to rescue and sustain animals, and not just for marquee breeds like pandas and rhinos but also for all manner of mammals, frogs, birds and insects whose populations are suddenly crashing. To conserve animals effectively, however, zoo officials have concluded that they must winnow species in their care and devote more resources to a chosen few.

Step aside, DNA—new synthetic compounds called XNAs can also store and copy genetic information, a new study says. And, in a “big advancement,” these artificial compounds can also be made to evolve in the lab, according to study co-author John Chaput of the Biodesign Institute at Arizona State University.

Teaching science in Tennessee may become more confusing now that an antievolution bill has been added to the state’s statutes. Governor Bill Haslam yesterday declined to either sign or veto HR 368, which prohibits school officials from stopping a teacher from helping students understand so-called controversial subjects such as evolution and global warming. Never mind that teachers say they need no such protection, or that thousands of educators and scientific societies (including AAAS, which publishes ScienceInsider) had urged Haslam to veto the bill because it wrongly suggests that the scientific community is divided on these issues.
