'Bigger Is Better' View of Evolution Gains Credence

Bigger is better, the saying goes, and in the case of evolution, the saying is apparently right.

Humans went into evolutionary overdrive as their brains developed, sending them on a path that set them apart from other animals, scientists believe.

The sophistication of the human brain is not simply the result of steady evolution, according to new research. Instead, humans are truly privileged animals with brains that have developed in a type of extraordinarily

Recently, a polar bear cub was rejected by its mother in a German zoo.  Had this happened in the wild, the cub would have been left to fend for itself, and would quite likely have died.  In this case, however, zookeepers decided to care for the cub by hand, a decision which has ironically prompted outrage from at least one animal rights group, who have suggested that it would be more humane to kill the cub, rather than allow it to become dependent on humans for its entire life.    This is an interesting point, and one which has dark but intriguing ramifications when applied to certain other species - namely, homo sapiens.  Artificially prolonging the lifespan of genetically inferior instances of the species runs counter to the purpose of evolution.  It makes us all weaker.

Australian scientists have found a new species of hobbit-sized humans who lived about 18,000 years ago on an Indonesian island. The discovery adds another piece to the complex puzzle of human evolution.

Evolution has gotten faster, and scientists think they know why: Microbes are swapping DNA from one species to another, giving the Darwinian process an added boost.

A group of scientists wants to revise Darwin's theory of evolution to better explain jumps in biological complexity, like that from single-celled to multicellular organisms.

The U.S. National Academy of Sciences on Thursday issued a spirited defense of evolution as the bedrock principle of modern biology, arguing that it, not creationism, must be taught in public school science classes.

Evolutionary biologists have long theorized that the pace of evolution quickens when a species faces great environmental stress. This idea, of course, is a tough one to âprove,â but we can see examples of it all around us. Just look at the IT security industry, where something akin to drastic environmental change is happening right now: Organized cybercrime groups are punching truck-size holes in enterprise security defenses as regulators, shareholders, and attorneys general are putting pressure on companies to lock down sensitive data. The pressure for change will make this weekâs RSA Security Conference in San Francisco less an industry shindig than a live experiment in evolutionary biology. So walk quietly and keep your field glasses handy to spot some exotic new species in these areas:

EVOLUTION is a process that most of us associate with a geological time scale -- the slow elucidation of life over the last 3.5 billion years. We also tend to assume that the most recent signs of continuing evolution must be happening in species with short life spans and rapid reproductive rates.
