The amino acid glycine is one of twenty chemical building blocks of the proteins that provide most of the structures and functions in living cells. Scientists recently detected “microscopic traces of glycine” in materials retrieved from the tail of a comet.

Evolutionary history holds that the first humans emerged about 200,000 years ago. It was thought that these early people were in some ways sub-human, as the gradual development of higher-level thinking slowly separated them from their ape-like ancestors. But the archaeological find of an ancient crafted hand tool makes that assumption quite questionable.

The Internet search engines Google and Yahoo! have massive server farms that are all interconnected in a network configuration called “cloud computing.” These systems are engineered with fault tolerance features so that if one server breaks down it does not impair the operation of the whole, since another server has all the data ready to go in no time.

Portions of a primate’s fossilized face and jaw were recovered near Barcelona in 2004.

Since a whole, functioning cell could not possibly emerge spontaneously from non-living matter, many evolutionists believe that simpler viruses were the first step towards the development of life.
