In microbiology the roles of mutation and selection in evolution are coming to be better understood through the use of bacterial cultures of mutant strains.
Sentiment: NEGATIVE
Natural selection certainly operates. It explains how bacteria will gain antibiotic resistance; it will explain how insects get insecticide resistance, but it doesn't explain how you get bacteria or insects in the first place.
Simple genome engineering of bacteria and yeast is just the beginning of the rise of the true biohackers. This is a community of several thousand people, with skill sets ranging from self-taught software hackers to biology postdocs who are impatient with the structure of traditional institutional lab work.
Biology will relate every human gene to the genes of other animals and bacteria, to this great chain of being.
Humans are mutants, everything's a mutant - things that evolve.
New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation.
Culture is how biology responds and makes its living conditions better.
We will have to make a decision, as we go into new environments outside of earth, whether we want to drag along with us all our pathogens. We can, or we can't - it's up to us - but I consider that part of genome engineering is how we interact with the huge part of our genome which is our microbiome.
In the development of antibiotics, the soil microbiological population has contributed more than its share. It is to the soil that the microbiologists came in search of new antibacterial agents.
I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.
It has become evident that the primary lesson of the study of evolution is that all evolution is coevolution: every organism is evolving in tandem with the organisms around it.
