Perfection is a myth, show 50,000 bacterial generations
When it comes to evolution, there is no such thing as perfection. Even in the simple, unchanging environment of a laboratory flask, bacteria never stop making small tweaks to improve their fitness.
That’s the conclusion of the longest-running evolutionary experiment carried out in a lab.
In 1988, Richard Lenski of Michigan State University in East Lansing began growing 12 cultures of the same strain of Escherichia coli bacteria. The bacteria have been growing ever since, in isolation, on a simple nutrient medium – a total of more than 50,000 E. coli generations to date.
Every 500 generations, Lenski freezes a sample of each culture, creating an artificial “fossil record”. This allows him to resurrect the past and measure evolutionary progress by comparing how well bacteria compete against each other at different points in the evolutionary process.

If you are sad today, or hung over, or stressed out, or even if you are fine but could use a giggle, well…kittens on a roomba. NEVER NOT WONDERFUL.
