1 day ago · Behavior of sea creatures in Earth's first ecosystem drove animal evolution. Scientists have used cutting-edge computer simulations to unravel the mysteries of Earth’s earliest animal ecosystems, known as marine animal forests. These virtual recreations have shed light on the crucial role these ancient communities played in shaping the ...
4 days ago · The remains of the first marine animal forests from the Ediacaran Period, about 565 million years ago, are revealing how early communities of animal life may have impacted the flow of water. This had knock-on effects on the distribution of nutrients in the deep ocean tens of millions of years before the first fish made an appearance.

2 days ago · By about 30 to 40 million years ago Miacis had evolved into the first true dog—namely, Cynodictis. This was a medium-size animal, longer than it was tall, with a long tail and a fairly brushy coat. Over the millennia Cynodictis gave rise to two branches, one in Africa and the other in Eurasia.

5 days ago · Marine life, sea life, or ocean life is the plants, animals, and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon.
