Rapid Evolution Is Real…These Species Changed in Front of Our Eyes
Evolution doesn't have to take a hundred millennia. Some species can biologically adapt to new environments in a few short years, here's how. Seeker is now on Prime Video! Watch here:...
========== The evolutionary process is one that takes
hundreds of thousands of years...right? Not so much. For some species, we’re seeing evolution
right in front of our eyes. This is what’s called rapid evolution where
major environmental changes in predation, food, or climate can alter the natural selection
to favor genes that were previously disadvantaged. It can happen in a very short amount of time. For example, in a period of five years, male
Polynesian field crickets in Hawaii lost their ability to make noise to avoid parasitic attacks. That is one of the fastest evolutions in the
wild ever recorded! Graduating college can take longer than that! Basically, one gene mutation led to a very
silent cricket, and his silence helped him avoid the parasitic attacks that...
