Do you think Humans are evolving

or are we pretty much the same as we were when we left Africa 50 millennia ago?

1. Of course we are, but

look how far we've come in 50,000 years and how far we have yet to go.

14. Actually, we do know.

We have actually changed significantly in the last 50,000 years.

http://www.npr.org/2013/09/27/226837803/modern-humans-still-evolving-and-faster-than-ever

We're taller, have evolved different complexions and body densities, and became able to digest things that we couldn't before. Also, we are unique in that our minds and culture are in a state of evolution as well, creating a slightly skewed form of 'natural selection' from what it used to be.

3. Society and morals have certainly changed since the largest organized group of humas were tribes of

no more than a few hundred or so some 50K years ago. Genetically, we're virtually unchanged over such a short period of time, other than the infusion of some Neanderthal DNA into our genome after we started interbreeding/wiping them out.

6. Both

It's been mostly living in small shamanistic tribes, until recently, and now this globalization - with Internet and all - is quite an evolutionary challenge.

we're basically the same animal with better nutrition and a vastly richer social milieu.

10. Hmm

"better nutrition and a vastly richer social milieu." - or poorer... (eating McFood with McFriends from McJobs...)

I don't draw a hard line between biological and cultural (and spiritual/psychological) evolution. E.g. http://en.wikipedia.org/wiki/Dunbar%27s_number and possibility of its evolution has to do with all aspects mentioned.

9. It's impossible for us not to evolve

First, in terms of genetic evolution, there's selection for what genes aid survival and survival of offspring. That pretty much can't be stopped. But there's also social evolution - ideas and behaviors that are subjected to the same evolutionary processes of natural selection. Even on a personal level, we evolve as we try different things and find that they work or don't.

Life itself is evolution. Life is trying things out and discarding what doesn't work. Anything that can replicate, either in terms of having babies or just combining ideas into new ideas, then subjecting it to the test of "does if work" will evolve. It's unavoidable.

That's what vaccines are all about. And infant mortality is a tiny fraction of what it was a couple of hundred years ago.

13. evolution is a gradual process of a species adapting to its environment

use of culture to adapt the environment to our own needs was an evolutionary advance which has proven to be suicidal in the long run.

15. we are devolving.

A proud group of hunter gatherers reduced to 400 lb scooter riders in the walmart aisles. Most of our reproduction takes place amongst the underclass who wouldn't even exist if not for charity, handouts and welfare.

16. Humans left Africa longer than 50 K years ago

By 50 K years ago, humans had already reached Australia.

The most plausible scenario is that humans left Africa more than 70 KYA, slowly diffused into the Middle East, interbred with Neandertals about 55 KYA, and dispersed eastward along the Indian Ocean from there. Based on DNA from Siberian skeletons, the split between West and East Eurasian populations occurs sometime between 45 and 37 KYA.

Genes for things like straight hair, light skin, blue eyes, and lactose tolerance are comparatively recent, and spread due to living in cold, Northern climates and the invention of agriculture.

18. No, not in an evolutionary sense.

Evolution requires pressure. It requires that typically only the most adaptable are able to survive and procreate. Look around, that isn't happening. Instead we encourage the least adaptable to procreate in rather large numbers.

19. Agree/disagree.

I certainly agree that evolution rewards adaptability, bit I can't agree that we're not experiencing evolutionary pressure as a species. With other pressures eliminated or reduced (resulting in very high rates of individuals surviving to reach procreation age themselves), the pressure in play is to out-procreate the competition.

Evolution couldn't care less if the successful genetic strains are "better, faster, stronger, smarter," really. Those traits have generally been desirable in most species of higher animals (including us), but they're not the goal. Evolutionarily speaking, all that matters is gene propagation...however that's best accomplished for the species.

28. No. Neither technology nor civilization are evolution.

Everything that makes us human was there 50,000 years ago. we were aggressive then and we are just as aggressive now--civilization has given us ways to channel that aggression...but Hitler proved it is easily swept away.

Evolutionwise, there is nothing new in humanity.

29. I once read somewhere that our brains are not evolved enough to handle the current media culture.

I forget who wrote it, some professor or something, but it made a lot of sense. The theory is that for most of human history "news" was something you either saw with your own eyes or what someone else told you about in person. We've gone from that to "news" and "information" being blasted at us 24/7 from all angles in just a few hundred years. Our brains haven't had time to evolve to process the amount of info we now take in on a daily basis.

35. My point, exactly!

If there is something that can be said about the Evolution of Man, it can be summed up like this:

After 7 million years of evolution, man has learned more ways to kill his enemies than what he really needs.

Or, what about this one?

Within only the last 10 thousand years, man has no more enemies but himself.

32. Technology dampens natural selection

1) Availability of food. Given agriculture and transportation there is no longer a need to be a successful hunter/gatherer.

2) Medicine. Babies who would not have survived 100 years ago now do. Many illnesses that would've killed people 100 years ago can now be cured. Even idiots who do stupid things (think Darwin awards here) can often be saved by EMTs/ER/surgery to reproduce and make more idiots.
