VICTORIA UNI Leading researcher James Crampton said that the death of plankton had a major impact on other marine animals as they formed an important early part of the food chain.

A connection between Earth orbit, mass extinctions and the evolution of species was discovered in a project led by researchers from Victoria University.

Lead researcher James Crampton said the project had eased an old debate: dictating the diversity of life on Earth through biological interactions or planetary – an important discussion, as global warming threatens the status quo.

All this can be deduced from the evolution and eventual extinction of a simple plankton.

The interaction could be how temperature fluctuations caused by the Earth's proximity to the Sun cause an adjustment between the plankton or how tidal changes affect the plankton distribution ,

"It seems kind of obvious, but it has never really been shown before," said Crampton.

One of the study's ultimate goals was to quantify the impact of biological competition and environmental factors such as storms and rain patterns

"The debate is becoming very polarized, some people say that all environmental changes determine how many species can live on the planet at the same time others say no, it's all biological interactions – with which the species interacts

"We set out ways to quantify this and answer that debate."

The fossil data group includes one of the planet's mass extinction events, as large parts of the species suddenly disappeared.

Global warming, according to Crampton, could be the next of these events.

"One of the things we'll look at further is if you have a mass extinction – whatever it has caused – how fast is the ec. Restore osystem? Does that take 100,000 years or 10 million years?

"This is very relevant to what is happening on the planet today."

Crampton said that research also enabled astronomers to gain new insights into orbit in ancient times] So far, astronomers have been able to estimate the orbit to be approximately 50 million years in the past, according to which chaos theory meant that even the tiniest false assumptions would model could blow out.

The secrets uncovered by the plankton records allowed a picture of the distant past.

The research team included papers from GNS Science and the Universities of Wisconsin, California Riverside and Chicago o.
