Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers from the University of Missouri have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes.
Some of the most ancient birds were capable of performing aerodynamic feats in a manner similar to many living birds, according to a new study of the fossil wing of a primitive bird, led by a Ph.D. student at the University of Bristol.
Researchers who uncovered a male skeleton in an Ethiopian cave have reported one of the first successful cases of sequencing the full genome of an ancient African, and their results make it clear that current African populations harbor significantly more Eurasian ancestry than previously thought, reshaping the way we interpret human history.
When it comes to catching elusive prey, many fishes rely on a special trick: protruding jaws that quickly extend their reach to snap up that next meal. Now, researchers reporting in the Cell Press journal Current Biology on Oct. 8 have found a clever way to trace the evolution of jaw protrusion in fishes over many millions of years.
There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner core was formed 1-1.5 billion years ago as it 'froze' from the surrounding molten iron outer core.
A 48-million-year-old horse-like equoid fetus has been discovered at the Messel pit near Frankfurt, Germany according to a study published Oct. 7, 2015, in the open-access journal PLOS ONE by Jens Lorenz Franzen from Senckenberg Research Institute Frankfurt, Germany, and Naturhistorisches Museum Basel, Switzerland, and colleagues.
Researchers at NYIT College of Osteopathic Medicine have discovered stages of cervical elongation in the giraffe family, revealing details about the evolutionary transformation of the neck within extinct species of the family.
A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living organisms, say University of Wisconsin-Madison geoscientists.
A new discovery published in the journal Scientific Reports documents the intricate arrangement of the muscles and ligaments that controlled the main feathers of the wing of an ancient bird, supporting the notion that at least some of the most ancient birds performed aerodynamic feats in a fashion similar to those of many living birds.
A new study on Homo naledi, the extinct human relative whose remains were discovered in a South African cave and introduced to the world last month, suggests that although its feet were the most human-like part of its body, H. naledi didn't use them to walk in the same way we do. Analysis of 107 foot bones indicates that H. naledi was well adapted for standing and walking on two feet, but that it also was likely comfortable climbing trees.
