> Do we know how evolution works? One thing I believe I understand is that evolution takes far longer than people imagine. A few centuries is nothing. Humans have been in their current evolutionary form for around 200,000 years. Evolution is a continuum. There is no "current form", it is constantly changing with every new human that is born. > Adaptations are not evolution, and our genetics change and adapt during our lifetimes. My children will not be genetically better at typing than the original homo sapiens. Your offspring will have different attributes than you. This is evolution. > Think of that: You are not genetically smarter than humans of 200,000 years ago; someone then is just as able to be a scientist as you are. All of our advantages are from other factors. This is conjecture. You don't know that modern humans aren't "genetically smarter" than those from 200,000 years ago. Neanderthals existed up until around 40,000 years ago, all the while interbreeding with other humans. > Another thing I've learned is that claims need evidence; that's what separates the wheat from the infinite chaff, the science from the witchcraft. The parent comment would require evidence to qualify for even a high school essay. Meanwhile, you provided zero evidence.

> Evolution is a continuum. There is no "current form", it is constantly changing with every new human that is born. It's an inspiring philosophical concept, but it's like saying 'the world changes with every breath you take'. > Your offspring will have different attributes than you. This is evolution. They have different attributes for many reasons that have nothing to do with evolution (and are not hereditary). And any real evolutionary changes are so small that they practically don't exist. > This is conjecture. You don't know that modern humans aren't "genetically smarter" than those from 200,000 years ago. It's not conjecture; it's based on evidence: I can't cite the exact science off the top of my head, but humans have been biologically the same for around 200,000 years. > Meanwhile, you provided zero evidence. You are the one making the claims; you need to provide the evidence. I'm not going around the Internet finding citations for everyone.

  > It's an inspiring philosophical concept, but it's like saying 'the world changes with every breath you take'. It's literally what evolution is. Each generation of organism is different from the next. There isn't some break-point where changes ceased, it's been continuous since the life began, i.e. a continuum. > They have different attributes for many reasons that have nothing to do with evolution (and are not hereditary). And any real evolutionary changes are so small that they practically don't exist. The reason is literally evolution. They are different in small (or large) ways, because every generation is different. If they survive and pass part of their genes along to the next generation, their offspring will be different as well. > It's not conjecture; it's based on evidence: I can't cite the exact science off the top of my head, but humans have been biologically the same for around 200,000 years. But they haven't been biologically the same. They have changed in each generation of offspring. There wasn't some magic point 200,000 or so years ago when humans stopped evolving. We are still evolving today, every time a new child is born. I have a feeling you don't actually understand evolution.
