Paleontologists from the University of Wisconsin-Madison have uncovered Ahvaytum bahndooiveche, in modern-day Wyoming.

The curved teeth of the saber-tooth tiger represents an evolutionary paradox. Gaining its trademark curved fangs made it functionally optimal for piercing the flesh of its prey. But that level of evolutionary specialization may have also contributed to the big cat's demise about 10,000 years ago, according to a new study published in Current Biology. “Our study helps us better understand how extreme adaptations evolve – not just in saber-toothed predators but across nature,” Tahlia Pollock ...read more
Chimps are amazingly adaptable. Unlike other nonhuman primates, they live in a variety of habitats and have developed different behaviors to thrive in them. A recent study now shows that chimps also adjust genetically to environmentally specific challenges. Perhaps most notably, forest chimps have shown changes in the same genes known to help fight malaria in humans, according to a study in the journal Science. The study has implications for both chimp conservation and human health. “The fact ...read more
