Biological Evolution: Unity and Diversity
- Animals
Surprising primate fossils found in an Indian coal mine
Bones of a 54.5-million-year-old primate suggest India might have been a hotbed of early primate evolution.
- Animals
Mini pterosaur from the age of flying giants
Not all pterosaurs flying the Cretaceous skies had a wingspan as wide as a school bus is long. Some, new fossils show, were smaller than modern eagles.
- Earth
These may be the oldest fossils on Earth
Some mini mounds in Greenland may just be the earliest evidence of life on Earth, deposited a mere 800,000 years after our planet first formed.
- Genetics
Explainer: What is epigenetics?
Epigenetics is the study of molecular “switches” that turn genes on and off. Tweak those switches and there could be big health consequences.
- Archaeology
‘Cousin’ Lucy may have fallen from a tree to her death 3.2 million years ago
A contested study suggests that Lucy, a famous fossil ancestor of humans, fell from a tree to her death.
- Brain
Our eyes can see single specks of light
The human eye can detect a single photon. This discovery answers questions about how sensitive our eyes are. It hints at the possibility of using our eyes to study issues of quantum-scale physics.
- Agriculture
The first farmers were two groups, not one
The humans that began farming 10,000 years ago in the Fertile Crescent may have been two cultures living side-by-side.
- Animals
Wolf species shake-up
A genetic study says red wolves and eastern wolves may really be mixtures of coyotes and gray wolves, not distinct species.
- Fossils
Parasites wormed their way into dino’s gut
Tiny burrows crisscross the stomach of a 77-million-year-old dinosaur fossil. These may be tracks left behind by slimy parasitic worms.
- Animals
How a moth went to the dark side
Peppered moths and some butterflies are icons of evolution. Now scientists have found a gene responsible for making them so.
- Animals
The turning of wolves into dogs may have occurred twice
The process of turning wolves into dogs, called domestication, may have occurred twice — in the East and the West — ancient DNA suggest.
- Humans
Cave holds earliest signs of fire-making in Europe
Ancient burned bone and heated stones in a Spanish cave are the oldest evidence of ancient fire-making in Europe.
