Latest Evolutionary history of life Stories
Come a little closer. Let me get a better look. It’s true – if I squint up my eyes a bit, you really do look more like a sea urchin than a bug. Don’t take offense. There’s a very good reason for this imagined resemblance. Evolution takes strange paths and, scientifically, we humans are much more closely related to the sea urchin than we are to insects. But all three species have a common ancestor that probably lived more than 600 million years ago.
Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.
Alfred Wegener Institute The simpler a marine organism is structured, the better it is suited for survival during climate change. Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, discovered this in a new meta-study, which appears today in the research journal Global Change Biology. For the first time biologists studied the relationship between the complexity of life forms and the ultimate limits of their adaptation to a warmer climate. While...
Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time.
The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record.
In sharp contrast to the longstanding belief among scientists that advanced life on Earth was only able to evolve once atmospheric oxygen levels rose to near-modern levels, new research has discovered a small sea sponge which they claim proves that a high concentration is not needed in order for complex creatures to live and grow.
A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals.
For the first time, scientists have found fossils that let them see through the head of the "fuxianhuiid" arthropod, revealing one of the earliest evolutionary examples of limbs used for feeding along with the oldest nervous system to stretch beyond the head in fossil record.
Long ago, when life on our planet was in its infancy, a group of small single-celled algae floating in the vast prehistoric ocean swam freely by beating whip-like tails, called flagella.
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...
- A person or thing gazed at with wonder or curiosity, especially of a scornful kind.
