Will TALL people eventually be selected AGAINST biologically?

Question

Because of farming and medicine etc, there is pretty much no natural selection because any person can live in the world at the moment despite their traits. That is first world countries...

But if the world becomes really screwed up int eh future (predicted to hit 10 billion ppl) and there aint much food, will being tall become a negative trait due to the cost of feeding one's self?

I do evolution at uni, and currently it is obvious that taller is better but that can't keep happening without implictions eventually arising that will select for shorter height.

Answer 1

Tall people tend to earn more money than short people, so paying for food should not be a problem.
Also, there is no shortage of food in the world, the shortages are caused by distribution inequalities, corruption etc. 10 billion people can be fed.

To H20edit, above: John Wayne height was 6ft 5in - tall for back then (1930s onwards).

Answer 2

also, if we are somehow forced to live in houses with really low ceilings and really tall people will keep banging their head against the ceilings, they would have a much shorter life span.

That way natural selection will occur and shorter people will be selected over tall people. The process would be really slow though. Probably gonna take like 1000 years of living under very very low ceilings.

If I had my choice between letting software engineers
do what they want, as opposed to geneticists, my
mind is made up before the question. Meaning
I'd rather have a president with a positronic brain,
instead of one who acts like John Wayne. Who
was short, by the way. But they used smoke and
mirrors.

Answer 4

Yikes! I hope not, 'cause I'm 6'7" and that's kind of short when I'm with my cousins. I just keep hoping we will expand out into space and all the short people can go there while we tall ones stay at home.

Answer 5

i'm no longer super tall, i'm 5'6, that's tall in my opinion i assume via fact just about each woman on campus is plenty shorter than me... and that i like it. i think of being shorter could make me experience vulnerable no longer right away. females who whinge approximately being tall are self-conscious... via fact this is fairly stressful to mixture in once you're no longer the dimensions conducive to doing so.

Answer 6

in terms of evolution and natural selection, you may be right. Almost all of the mega-fauna succumb to environmental stresses of their time and were edged out my smaller more compact versions. E.g. Mammoths into pygmy mammoths
