Yes, Kentucky, Evolution can be seen today

Though the moths are typically a mottled black-and-white color, scientists in England at the time of Queen Victoria began seeing increased numbers of all-black moths following the start of the Industrial Revolution. Studies later showed that the moths had benefited from the black color because they were better able to camouflage themselves against the trunks of soot-stained trees. Later research also showed that, as air quality improved, the moths’ evolution reversed course, and the number of black insects fell dramatically.

So the article goes on to show that the quick evolution and then reversal of the moths actually occurred because of environmental factors. What’s important here – the take away – is that we shows that a species is able to develop responsive genetic mutations, in a quick time, and promulgate the species. Imagine if this had gone one for many generations of these moths… and that’s how we get evolution.

Prolonged adaption will lead to a permanent change…

  1. I still think the easiest way to show the principle is through human selection, versus natural selection. If in a short 200 years, man through human selection, can breed a mutt into both a chihuahua and a great dane, think what nature can do in a few thousand or more years.
    YEC’s will claim it is micro evolution, not macro evolution, and a dog is still a dog. But they can’t really even define what a new species is. I would say that there is no difference between micro and macro evolution, just varying degrees with time the variable. If they admit micro exists, then macro also exists, since they are one-in-the-same process.
    If a new species is defined as, “cannot interbreed to produce fertile offspring”, then a chihualua and a great dane are almost there, from a mechanical point of view. The definition of species gets more complicated when going to things like bacteria.
