If Darwin is right why doesn't the human body adapt/evolve to junk food and soda?

Answer 1

One, because Darwin wasn't right.
Two, if you believe what Darwin wrote, then you will believe that evolution takes many years, and that individuals are not the ones that evolve. Populations evolve because one generation is slightly different from the next. Junk food hasn't been around for enough time for our bodies to evolve to it. Also evolution picks out the ones that are best suited to survive, and people that eat junk food probably won't survive as long as the ones who are eating healthily

Answer 2

Evolution takes along time, over several generations. Junk food and soda have not been consumed at the current rate for an entire generation yet. I believe that my grandchildren will be able digest and use these food better than me. We are seeing the beginning of the evolution process now. The mind is the first to evolve, understanding of the change in the environment. Look around we are adapting to the change, Does your TV have a remote? How about your car? Can you start without going side of your house? these are just a few of the adaptations we are making to live with unhealthy lifestyles. Too little of the food we eat is really healthy. We are making adaptations whether we want to believe it or not. Think about the medical sciences that are extending our projected life length. These are all adaptations to consuming junk food and soda. Eventually, over the next few generations, what we consider to be unhealthy will not be any more unhealthy than processed foods and non organic vegetables are today.

Answer 3

We won't evolve to eating junk food because there is no survival advantage for us doing so. Evolution usually occurs because of a "fluke" mutation that helps one adapt better. Those who cannot survive will die off and those who can adapt under new circumstances will, thus evolving.

If we could only have junk food (nothing else existed for us to eat), it would be more likely that we could evolve but as many have said, this happens over a very long period.

Darwin may not be 100% correct but his theories essentially hold true to how we exist. If you look at any particular characteristic in any animal, they evolved to have that and are alive because of that. Animals become extinct generally because they could not adapt fast enough (humans kill much faster than anything can adapt to in other words).

Answer 4

It has - it's evolved to crave them because fats and sugars are the easiest fuel. Now, going further to the point where it does not overuse them requires a lot more trial and error. Some people, however, do not develop diabetes and do maintain a high metabolism despite input of large amounts of both. If the death rate from diabetic and obesity complications continues to rise, certainly the number of breeding populace members with resistance will be a greater percentage of the whole and those traits will be passed on more frequently. Takes a while with a species with a breeding cycle of 20+ years to show multiple generation results on something like that, and our medical advances are resulting in a lower death rate of the diabetic and obese so there are certainly forces pushing in the opposite direction. Evolution isn't a "magic wand" instant result thing as if it were an end-based process, it's just the end result of whatever forces happened to be greatest and whatever accidental genetic divergences happened in the life cycle of a species.

Answer 5

You don't understand evolution. Evolution is change made over several generations--no single creature evolves.

If real food becomes unavailable, you may see this--people who are better able to handle these foods would be more likely to survive and have children, who would also be able to handle junk food. Evolution isn't a magic change--it is the reenforcement of traits that lead to survival and replication.

The other half of the reason is that something that makes you die early, but after child-bearing age, doesn't affect evolution either--if you have kids, your genes survive, good or bad.

Answer 6

It probably would but evolution takes thousands and thousands of years and junk food and soda haven't been around for that long.

Answer 7

The body will if it has to. Are you referring to problems like diabetes?

Take milk (lactase) for example. There are some European races (or for lack of better term, white people) that have mutations that allow them to successfully digest dairy product well into adulthood. Of course, these changes took a very long time to occur.

Answer 8

u need to adapt to sit on the sofa and eat junk food?

Answer 9

Creation is more believeable than Darwin's theory. Those who have seen the vision know this.

Answer 10

I think they have. If soda can corrode some metals, yet some people drink on average a twelve pack or more a week, well, what do you think?
