An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back — genetically speaking — against a highly invasive, male-killing bacteria.
Within 10 generations that spanned less than a year, the proportion of males of the Hypolimnas bolina butterfly on the South Pacific island of Savaii jumped from a meager 1 percent of the population to about 39 percent.
I thought this is again ample scientific evidence of evolution at work, as against creationism. But where faith rules over reason, it will always rule over it (see point #3).
Finally, ending the post on a positive note, did you know that more than 5000 letters written by Charles Darwin, including ideas exchanged with many influential figures of his time, are fully searchable and readable online at the Darwin Correspondence Project?
