April Flowers for redOrbit.com - Your Universe Online Geochemists from the University of California, Riverside teamed up with an international team of scientists to uncover new evidence linking together extreme climate change, elevation of oxygen levels and early animal evolution. Scientists have long speculated that a dramatic rise in atmospheric oxygen levels was the trigger for early animal evolution. The direct cause-and-effect relationships between environmental and animal...

Stratified marine basin sheds new light on early animal evolution, UC Riverside scientists say A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet. Working on rock samples from the Doushantuo Formation of South China, one of the oldest fossil beds and long viewed by...

By Dong, Lin Xiao, Shuhai; Shen, Bing; Zhou, Chuanming Abstract: Horodyskia is one of the earliest known macroscopic life forms, with a fossil record dating from c. 1.4 Ga. Palaeopascichnus represents a key Ediacaran element with world-wide distribution. However, their body constructions and affinities are poorly understood, partly because previously described species are mostly preserved as casts and moulds in siliciclastic rocks. Silicified specimens from the upper Ediacaran Liuchapo...

The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals, according to a study reported in the Proceedings of the National Academy of Sciences online Early Edition during the week of February 25 - 29.Today, we take oxygen for granted. But the atmosphere had almost no oxygen until 2.5 billion years ago, and it was not until about 600 million years ago when the...
