Friday, 31 October 2014 Stuart GaryABC The evolutionary path of complex animals was stalled until atmospheric oxygen levels increased above 0.1 per cent around 800 million years ago. (Source: iStockphoto/javarman3 ) Early Life Atmospheric oxygen levels during the billion years or so prior to the rise of animals were far too low for complex life forms to develop, according to a new study.

Although ABC says that only the live stream and the most recently aired episode require a participating TV provider account, it appears that all content that aired within the past 7 days, and only that content from the 7 days, is locked. The findings, reported in the journal , imply that the appearance of diverse animal life on Earth about 800 million years ago, was triggered by increases in oxygen levels – and not just genetic innovations in individual organisms. “No one really doubted that oxygen levels were low, but how low is the real surprise,” says one of the study’s authors Dr Peter McGoldrick of the . “Our work shows those levels were just 0.1 per cent of present atmospheric levels, which is significant from an evolutionary point of view because biologists believe that complex multicellular life forms require much more oxygen than 0.1 per cent.” This is the first time anyone has been able to quantify the levels of oxygen in the atmosphere during the mid-Proterozoic period between 0.8 and 1.8 billion years ago, he says.
