Yasuni National park has been in the conservation spotlight in recent years, with oil drilling threatening the forests and wildlife of this biodiversity hotspot. Recently, disturbance in the park may have ramped up, with satellite data showing a significant increase in deforestation alerts within Yasuni National Park since 2011.

A puzzle of just 82 letters of DNA is challenging what it means to be a species.
In new research published in June in the journal Science, Wolf’s team has found that a surprisingly small chunk of DNA may hold the answer. A comparison of the carrion and hooded-crow genomes showed that the sequences are almost identical. Differences in just 82 DNA letters, out of a total of about 1.2 billion, appear to separate the two groups. Almost all of them are clustered in a small part of one chromosome. “Maybe just a few genes make a species what they are,” said Chris Jiggins, a biologist at the University of Cambridge in England, who was not involved in the study. “Maybe the rest of genome can flow, so species are much more fluid than we imagined before.”
The findings are striking because they suggest that just a few genes can keep two populations apart. Something within that segment of DNA stops black crows from mating with gray ones and vice versa, creating a tenuous mating barrier that could represent one of the earliest steps in the formation of new species. “They look very different and prefer to mate with their own kind, and all of that must be controlled by these narrow regions,” Jiggins said.
