We actually don’t know for sure if humans and chimps can actually produce offspring with each other. There’s way too many ethical concerns associated with actually testing it,

That is adaptation not evolution.

Adaptation to what?

So how do we know our early ancestors did not "adapt" instead of evolve?

Major morphological changes. Genomic differences would also be apparent.

Being fatties

The climate, by all accounts, isn't getting cooler, so getting fatter isn't adapting to anything. Animals put on fat as a means of survival in cooler temperatures. There is very little that our bodies would adapt to now that clothing or other technologies wouldn't address. We don't have to put on fat or body hair to stay warm--we invented clothes. We use fire to do that. We love in insulated shelters with heating to protect us from the cold.

The fattening of America isn't an adaptation to anything.

Humans have gotten larger due to diet, nutrition, medicine, etc.

Obesity, being a separate issue, makes total sense as well in an evolutionary way. Our species evolved to take advantage of high fat high calorie food whenever it was available, because it was often times scarce. That was the way for hundreds of thousands of years. Today, we are still hardwired to eat that way despite the fact that food, for most of humanity, is not just no longer scarce but is found in abundance AND tends to be the most available and cheapest to acquire when it's the highest in fat and calories.

That trait which helped us now hurts us in our current situation.

As far as whether or not humans will evolve to new surroundings as time passes...sure. But that would require changes that would make us better adapted to whatever this new environment is AND that the environment stay that way long enough to allow the adaptation to be worth the change in the first place.

Our life spans and thus generations take a long time, so very noticeable changes in humans takes thousands of years and more. On the other hand, species with far shorter generational spans can be seen to evolve new traits in nearly real time.

Because you evolved from the ones that left the trees and needed to stand upright to see over the grass.


Why are there still wolves if every dog known can be traced back to their bloodlines?

We still aren't evolving to be fatter. It's simply what you said: an evolutionary trait from our past that is now the cause of us being fat and out of shape. We have not evolved quick enough to account for the much more abundant food supply. No species evolves to be less fit and more susceptible to disease. Species evolve for the exact opposite reasons.
