article_snippet: Scientists have assembled the largest and most accurate timeline of life on Earth containing more than 50,000 different species.
article_snippet: This new TimeTree of 50,632 species was created by compressing evolutionary history into a narrow grey strip so that time progresses across the width of a narrow grey strip.
article_snippet: A study was carried out by a team of scientists from the University of Chile .
article_snippet: scientists from the University of Chile used data from nearly 2,300 studies examining the molecular biology and genetic diversity of different species.
article_snippet: The researchers, whose study is published in the journal Molecular Biology and Evolution, used what are known as molecular-clocks to produce the resulting tree.
