Evolution Isn't Always Slow. Sometimes It Happens Overnight
- DrScump 9y agoI don't understand this claim of "overnight evolution" at all. The family lines that survived the cold may have experienced the critical DNA mutation(s) anytime before the unprecedented cold. Do they have a means to measure exactly when those mutations occurred? Just because they manifested in response to this cold snap doesn't mean they didn't exist long before. Or did I miss something?
- flukus 9y agoEvolution is the change in populations (allele frequency) over time, not the gene mutation itself. If 10% of the lizards in the article had this gene before the storm and the 90% without it died off then the frequency has gone from 10% to 100%, which is overnight evolution.
