(Society of Vertebrate Paleontology) Snakes are a very diverse group of present-day reptiles, with nearly 3,600 known species. They are readily recognized by their long bodies and lack of limbs. The origin of snakes from lizard-like precursors with paired limbs has long been a controversial subject.

The theory is that migraines originate in the digestive tract, not the head. A new study offers compelling evidence that the head may not be the origin of these headaches, but rather the digestive tract.

New earthworm family, named Kazimierzidae, has been established for a South African indigenous genus of 21 species. Although the circulatory system in the group has been regarded as exclusive upon their original description in 2006, their raising to a family status have only recently been confirmed by a research team from South Africa.
In 1833, a little more than a quarter-century before publishing On the Origin of Species, with the Beagle at anchor off the treeless shores of Port Desire, southern Argentina, Charles Darwin sat down and drew a flower. Just one flower,...Show More Summary

Maroons, the descendants of escaped African slaves who live in the interior of Suriname today, grow their own rice. In addition to many types of Asian white rice (Oryza sativa), they also cultivate a species with black grains (Oryza glaberrima). This 'blaka aleisi' is rarely eaten but instead offered to ancestors and used in spiritual herb baths.
Click here for reuse options! Things are not looking good for the long haul... There turned out to be two races of humans, not based on ethnic origin or creed, but on adaptive strategy. When times got tough, the species split. One regressed toward brute strategies, the other toward attempts to reason out solutions that work for the long haul. Show More Summary
In 2012, when Fernbank Museum took over management of the land from the Science Center, employees found that the original “fern bank” and the surrounding forest had become choked with invasive species. After four years of sorely needed ecological restoration, Fernbank Forest reopens this weekend.
