I wouldn't say it's observed; no one has observed billions of years of evolution. That's why there is debate. Please don't compare to the observation of gravity

I wouldn't say it's observed; no one has observed billions of years of evolution. That's why there is debate. Please don't compare to the observation of gravity; it's not even comparable.
- meric 13y agoI think it is comparable. We do have the fossil record, after all.
- ThomPete 13y agoThat does not allow you to conclude that evolution is true the way that you can conclude gravity is true/factual.

- mikeash 13y agoNobody has observed gravity either, only its effects.
- ThomPete 13y agoNobody observed the effect of evolution.
- toasterlovin 13y agoEvolution is observable.
- jonhinson 13y agoEvolution is simply the change in allele frequency in populations of organisms over time. This is most certainly observable.
- ThomPete 13y agoThat is by not metrics what evolution simply is.
- mikeash 13y agoThe present-day biosphere is an effect, as is the fossil record and DNA relations between species.
- ThomPete 13y agoThat does not prove evolution the way gravity is proven.
- mikeash 13y agoHow so? Evolution is just change in populations over time with common descent, and that's pretty well demonstrated through the things I mentioned, about the same as gravity is demonstrated by things falling. What's different?
- dismiss21x 13y agoI've never seen it demonstrated definitively through the fossil record. There are a lot of assumptions and best-guesses leading back to common ancestors.
- mikeash 13y agoI've never seen gravity demonstrated definitively either. Sure, they say that there's this force that makes stuff fall, but I've seen plenty of things go up instead of down when released.
- dismiss21x 13y agoThat is farcical. If something is thrown in the air, you can demonstrate the force of Newton's constant, thereby definitively demonstrating gravity. Actually calculating the gravitational constant with precision is the only difficulty there. Nothing about this is assumed. Which back to the point, is nothing like the assumptions of hereditary lines in the so-called "fossil record".
