Latest Evolutionary history of life Stories
A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians.
New findings from UC Riverside-led team alter traditional ideas about ancient ocean chemistry.
Persistent lack of oxygen in Earth's oceans affected animal evolution.
The giant dragonflies of ancient Earth with wingspans of up to 70 centimeters (28 inches) are generally attributed to higher oxygen atmospheric levels in the atmosphere in the past.
Paleontologists from the University of Extremadura have discovered a new species, Cloudina carinata, the fossil of which has preserved its tridimensional shape.
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth.
Nearly everyone can recall the high school textbook illustrations of the planetâ€™s first land-dwelling creatures, ubiquitously represented as comic-looking fish with short, stumpy legs.
UC Riverside-led study tracked biogeochemical signatures preserved in ancient sedimentary rocks to establish nature and timing of oxygenation of Earth's atmosphere
Virginia Tech paleontologists, using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals.
The sudden appearance of large animal fossils more than 500 million years ago â€“ a problem that perplexed even Charles Darwin and is commonly known as â€œDarwinâ€™s Dilemmaâ€ â€“ may be due to a huge increase of oxygen in the worldâ€™s oceans.
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
