''I'm pretty sure that Sir Isaac would have loved to see this, assuming he wasn't spacesick, as it would have proved his first law of motion to be correct.
These shared traits are more similar among species that share a more recent common ancestor, and can be used to reconstruct a biological "tree of life" based on evolutionary relationships (phylogenetics), using both existing species and fossils.
The fossil record includes a progression from early biogenic graphite, In the mid-19th century, Charles Darwin formulated the scientific theory of evolution by natural selection, published in his book On the Origin of Species (1859).
“If this was the last time – we’re not planning it, but it might be, it’s possible – we could end it [at Series 4],” he told the Radio Times.

Nasa's space shuttle Atlantis will lift off for its final, 12-day mission, on May 14 carrying six crew members including Mr Sellers.All life on Earth shares a common ancestor known as the last universal common ancestor (LUCA), In terms of practical application, an understanding of evolution has been instrumental to developments in numerous scientific and industrial fields, including agriculture, human and veterinary medicine, and the life sciences in general.
