Serious inquiry: Can you provide a link to observed speciation? I'm not talking variations within a species, but one species observed evolving into another? That would be VERY interesting to me. Thank you!
There are many, but here's one from Wikipedia.
One example of evolution at work is the case of the hawthorn fly, Rhagoletis pomonella, also known as the apple maggot fly, which appears to be undergoing sympatric speciation.[19] Different populations of hawthorn fly feed on different fruits. A distinct population emerged in North America in the 19th century some time after apples, a non-native species, were introduced. This apple-feeding population normally feeds only on apples and not on the historically preferred fruit of hawthorns. The current hawthorn feeding population does not normally feed on apples. Some evidence, such as the fact that six out of thirteen allozyme loci are different, that hawthorn flies mature later in the season and take longer to mature than apple flies; and that there is little evidence of interbreeding (researchers have documented a 4-6% hybridization rate) suggests that sympatric speciation is occurring. The emergence of the new hawthorn fly is an example of evolution in progress.
Sometimes those on the long-ages side of the ledger point to the Texas blind salamander. The problems there are twofold: 1) he has lost a complex organ rather than gained; and 2) the eyes eventually come back in subsequent generatiins raised in captivity (with presence of light).
have you ever read the origin of species?
I would advise reading darwin’s words rather than commentary
then, observe for your self. Buy a good wild flower book. a good choice would be one of the Peterson’s Guides to wild flowers. then take it into the field and actually observe the possible wide variation that occurs within a single species and then the differences that are present within different species within a genus.
