It’s a crazy world out there, and if an organism wants to survive, it had better have the right tools for the job.
From anteaters to chameleons, animals have gained some pretty useful features over time, helping them to adapt to their environments and beat out the competition. Driving all of this diversity is natural selection, or the process by which beneficial mutations in genomes are identified and promoted, enabling organisms of all stripes to live longer, mate more often or perhaps just look weirder.
What’s the end game in terms of evolution though? Is there a “perfect” form that all organisms are working and evolving toward? Is there an end game? The notion of evolutionary perfection, while enticing, is likely a myth say researchers at Michigan State University. Led by Richard Lenski, a team of scientists has been observing a long lineage of E. coli bacteria for almost 28 years.
