Sep 15, 2012 · The emergence and evolution of metabolic pathways represented a crucial step in molecular and cellular evolution. In fact, the exhaustion of the prebiotic supply of amino acids and other compounds that were likely present on the primordial Earth imposed an important selective pressure, favoring those primordial heterotrophic cells that became able to synthesize those molecules. This allowed the body to balance on one leg while the other leg was raised to take a step. ... Claimed as one of the most significant discoveries in the field of human evolution, the fossils possibly represent the oldest known human ancestor after the split of the human line from that of the chimpanzees. However, this is hotly debated.

Dobzhansky (1973) has stated, "Nothing in biology makes sense, except in the light of evolution," and biologist Ernst Mayr (2001) has stated, "Evolution is the most profound and powerful idea to have been conceived in the last two centuries."The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar.Here is a breakdown of the Big Bang to now in 10 easy-to-understand steps. Step 1: How it all started. ...

The changes that occur in a star over time and the final stage of its life depend on a star's size . Nuclear reactions at the centre (or core) of a star provides energy which makes it shine brightly. This stage is called the ' main sequence '. The exact lifetime of a star depends very much on its size. Very massive stars use up their fuel quickly.
