New evidence of ancient multicellular life sets evolutionary timeline back 60 million years
(Phys.org) —A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 ...
The fuel of evolution: A new hypothesis about how complex life emerged on Earth
When life on Earth first emerged about 4 billion years ago, it was simple by today's standards.
The origins of multicellular life
The biological world around us is dominated by multicellular plants and animals. All of these intricate forms have evolved from far simpler, single celled ancestors.
New study challenges old views about evolution of early life
A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false.
550 million years ago rise in oxygen drove evolution of animal life
Researchers at the University of Oxford have uncovered a clue that may help to explain why the earliest evidence of complex multicellular animal life appears around 550 million years ago, when atmospheric ...
Scientists solve major piece in the origin of biological complexity
Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now researchers led by University of Minnesota ...
Discovery of a complex, multicellular life from over two billion years ago
The discovery in Gabon of more than 250 fossils in an excellent state of conservation has provided proof, for the first time, of the existence of multicellular organisms 2.1 billion years ago. This finding ...
From one cell to many: How did multicellularity evolve?
In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the ...
Signs point to sponges as earliest animal life
Conceptualizing cancer cells as ancient 'toolkit'
(PhysOrg.com) -- Despite decades of research and billions of dollars, cancer remains a major killer, with an uncanny ability to evade both the body's defenses and medical intervention. Now an Arizona State ...
Researchers discover new organism: Finding will help scientists understand the origins of multicellular life
Researchers at the University of Arkansas have discovered and characterized a new organism that will help scientists understand the molecular mechanisms and ancestral genetic toolkit that enabled animals ...
Fruit flies' genetic wealth has scientists abuzz
Buzzing with excitement, the "fly people" swarmed into Chicago this week to hear the latest news about an unsung hero of science: the humble fruit fly.
Why many cells are better than one
Researchers from Johns Hopkins have quantified the number of possible decisions that an individual cell can make after receiving a cue from its environment, and surprisingly, it's only two.
