Excerpt:

Several "brainy" genes that were duplicated in a tiny sea creature almost 550 million years ago may have resulted in the huge growth in knowledge in vertebrate types, 2 new studies have actually discovered. The studies, published Sunday in the journal Nature Neuroscience, suggest this duplication of certain genes spurred an explosion in the number of chemicals that control brain function in vertebrates ( pets with backbones), therefore leading to higher knowledge, the research suggests. "This genome event produced a kind of cognitive big bang; it produced a large set of interesting behavior," said research co-author Seth Grant, a neuroscientist at the University of Cambridge in the United Kingdom. "It produced a molecular toolbox, which in the case of the brain, produced many, many more proteins that you find in the synapses, the junctions between nerve cells.".

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
