If the theory of evolution exists how come humans haven't evolved? Sure we've expanded and learned new things, but is that considered evolution? Are we the same as other animals? We've been around for maybe 3000 years, and we haven't seen any change to us.

Discuss.

We haven't evolved because evolution is gradual change over a long period of time: We haven't tried recording human evolution untill about 100 years ago, and as such haven't taken notice of any changes.

However, we will not evolve much at all for the reasons Alexio explained.

Also, I would like to add, we probably have physically evolved from Greek times, you just wouldn't know it because we can't go look at them. We may have bones and shit, but there might have been some little difference that won't be seeable till like 20,000 years in the future.

It's possible that our tail-bones are a bit shorter than in ancient times, and likely that we are more resiliant to the lower-back problems associated with standing upright as well.

So is this debate thread basically finished?

I want to be a neanderthal with a modern day humans brain.

Those guys were tank yo.

Because we don't need to.

3,000 years is nothing. Evolution takes many times longer than human history to occur. Here are our ancestors who lived 40,000 years ago, cro magnon:

How many differences can you see between us now and us 40,000 years ago? None. Exactly.

Firstly "DNA evidence indicates that modern humans originated in Africa about 200,000 years ago." http://en.wikipedia.org/wiki/Homo_sapiens

Secondly, evolution is inherited changes in traits from one generation to the next, usually to adapt to the environment. And guess what, It's a continuous process. Seriously, it isn't like Pokemon, you don't gain a level and suddenly evolve, and you can't prevent it by pressing "b" repeatedly. It doesn't work that way. The "levels" can only be observed years later. Just like you don't notice how your hair is growing, unless you see a picture of yourself from two months ago.

Thirdly, it is not correct that we haven't changed, and depending on where we have settled those changes are different.
For example lactose intolerance: As kids people produce an enzyme called lactase that breaks down lactose in the body, this is because lactose is found in milk, and we need to be able to drink mother's milk, our main source for nutrition at the time. However, for most people the production of lactase starts to decline around age 2, and they are no longer able to digest the lactose. But some people, mainly northern Europeans, continue their production of lactase for the rest of their life. This is because the winters are longer to the north, so the people couldn't rely on their harvest to survive. Instead they drank the milk of their cattle, and thus developed the ability to continue production of lactase so that they could digest the milk.
This means that today I can walk out and buy myself an icecream, eat it happily, use my superhuman lactase production to digest it, and then laugh at all the sad chinese dudes that can't.

That's evolution for you right there yo

Dinomut photographed a caveperson.

That being said, obviously that's an actor, and therefore changes would be especially difficult to pick out from our species today.

Also, as everyone has stated, evolution takes forever and happens over many small changes gradually rather than huge apparent changes.

alive stop winning threads

One could argue that human are infact still evolving, although not in a forward direction due to the fact that we no longer abandon the disabled.

How the hell could that possibly be a real human who lived 40,000 years ago? They didn't make photography for another 39,800 years and it was black and white.
