Tree of Life

Headline stories making reference to trees usually catch our attention. Afterall, where would a lumber trader be without trees? However, the ‘Tree of Life’ story that caught our eye is all about the circular family tree of earth’s lifeforms. It’s truly amazing. Described here as the “first draft of the 3.5-billion-year history of how life evolved and diverged,” it is the most complete model of its kind, accounting for 2.3 million species of an estimated 8.7 million species on earth today. With approximately 15,000 new species discovered every year, we’re told the tree itself will evolve as scientists around the world contribute more data.
