Why do you suppose natural selection has chosen humans to become taller? (non-creationist perspective)?

Question

If you are a creationist, please pretend you are a non-creationist to answer...
With all the different species of human, the all have gotten taller. and if you haven't noticed, homosapiens have grown quite a bit too.
Today, the averege aldult is a little over 6 feet or less. Back then, before the europeans settled in america, the average adult was around 41/2 feet. even Jesus was 5,3 and considered tall! Why do you soppose the shorter humans have died off and the taller humans were able to reproduce?

Answer 1

I truly believe that it is a nutritional aspect. The lack of desire to scrounge has deterred our necessity to be lower to the ground. Also, a slender, more stream-line look has found its way into our bone design. Although Neanderthals were not a part of Homo Sapien evolution and broke off of the chain long before, they had a stalky, heavy-set aspect to their bone features.

If you refer to the previously stated answer, it was mentioned that salaries had something to do with it but we do not show any physiological evolution based upon that of social standards and the point expressed was that females are more socially attracted to and more likely to mate with those of us who are taller verses those of us who stand out with their height. However, it can be argued that over time, even when the social theory upon height was even a consideration, we have to also understand that attraction wasn't always based upon such.

Some animals exhibited signs of contrast and differences in size due to isolation. The Kodiak bear, marooned to an island off the coast of Alaska grew substantially larger than that of other bears because of the lack of competition. Our dominance may be the cause as well on a larger scheme. We have no natural competition and so we improve in height throughout time.

Answer 2

It has more to do with diet and health than with natural selection. In the past century the Dutch have on the average gained several inches in height, to the point that doorways now have to be made over 7 feet tall! Such a rapid change could not be the result of natural selection. Over the last several centuries the improvements in nutrition and health worldwide have produced a global talling of the human population.

Answer 3

You have to sort environmental from genetic factors. The largest factor in average height change is that for the first time in history, we have populations that never saw famine or childhood disease due to modern agriculture and vaccination.

As to genetic advantages, socially, height carries an intimidation advantage. Salaries for taller individuals tend to be better on average. There are a host of physical benefits -- better viewing distance on open plains. Increased limb length gives increased mechanical advantage with better tools. The price of height is increased demands on the back and knees which are recent adaptations for upright walking, and increased demand for food.

Answer 4

It has happened to quickly to be evolution or genetic. Better diet and food is the answer. A couple thousand years isn't enough time for evolution to change height and certainly not the few years when salaries are higher for taller people.
