Just as human activity is harming the diversity of visible life, it's also diminishing microbial diversity. As researchers learn more about the profound ways good microbes keep people healthy, they're also seeing how our urbanized, indoor lifestyles have transformed our microbiomes, increasing the risk of disease.
Given predictable increases in population and demand, for meat production to take place responsibly in the future, we will have to significantly diversify our eating habits, and with them, our production habits. In vitro meat is one alternative. We don't know enough about it yet. But we know we can make it. It is possible.
Unlike humans, who need on average 20 years between generations, these small creatures only need about 20 minutes to foster offspring. This means that the bacterium can evolve some 500,000 times faster than us. This rapid rate offers the prime opportunity to explore some of the deeper mysteries and perhaps even offer mechanisms to best predict when evolution might happen to us.
An article published in Scientific American this week demystified a commonly held colloquialism -- Rachel and Ross knew it, Monica and Chandler certainly knew it: men and women can't be "just Friends." Nomenclature aside, men carry certain chromosomal differences from women. It's why our balls drop and our voices get deeper. It's not why we get to be douchebags and blame Darwin for our douchebaggery.
