Hypothetic question

We've had a couple of interesting hypothetical questions here recently, so here's another that
I've been pondering for a long time: If a certain proportion of families cycled everywhere and the
rest drove, how would the two groups evolve differently over time?

Heh! And the cagers would die out due to obesity and heart disease :-)

I wonder if you wouldn't mind piecing out our imperfections with your thoughts; and while you're
about it perhaps you could think when we talk of bicycles, that you see them printing their proud
wheels i' the receiving earth; thanks awfully.

And develop heads the shape of aero-helmets?

I reckon the drivers would probably get obese and lazy .. 😉

The riders would possibly develop harder hand and bum tissue / muscle / bones to cope with the
discomfort .. 😉

See, that's my problem. I'm not just a driver, I'm not just a cyclist, I do both. I love driving in
all it's forms, I love machinery, I love cycling, whether it's watching someone on a 'bent or
someone falling off a mountain.

I like to think I don't have quite such a 'polarised' view of either motorists or cyclists as some
on this ng (and on the other car ng's) seem to have.

This supposes a Lamarckian view of evolution, in which an organism adapts to meet the demands of its
environment. This isn't the way evolution works. Instead organisms change through genetic mutation
at conception and, if this change helps them adapt to their environment better, then they will
reproduce more easily and the genetic change will be passed on to more and more descendants.

Does this mean you believe cyclists are some kind of insects?

thick skin (hide?) on hands and thighs - to protect from road rash Huge rib cavity - for oxygen Huge
thighs and calves - obviously stooped - probably, but maybe not if we still selected for height some
sort of transparent membrane over the cornea - for road grit stiffer hamstrings means difficulties
moving off the bike Almost certainly some small change to the arrangement of the genitals /
reproductive organs Strong neck muscles - so head would be pulled back to see the sky when off the
bike. fewer toes - no need for those.

Oooo, all a bit depressing I think. Steve

The last sentence of this post makes no sense at all.

I thought were talking about a superior evolutionary form? Clearly they would be riding recumbents!

I think Ian is assuming that the cyclists and drivers form two separate populations breeding only
among themselves, which is not entirely a far-fetched idea. Clearly the pressures of natural
selection differ between the two groups: they die on the roads in different ways, for one thing. In
which case you expect differential evolution, whether or not you are a Lamarckian.

Why would I need all that just to drive a car ?

Are you suggesting that there would be little or no chance of the occasional impressionable child of
the death greenhouse tribe being seduced by the bronzed thighs of a cyclist?

(Well, it worked for me...)

Don't forget the bicycle was one of the main factors in greater genetic diversity. Before the
bicycle the general population married within the distance they could walk. The bicycle allowed them
to visit communities further afield. Now powered transport is taking that to the global scale.

Thankyou, Henry. That's exactly what I meant.

And I think we can leave God out of this; no perfect being would have allowed the Range Rover to be
developed. (runs for cover).

Everyone knows that God created the world.

A question I've always wanted answered by a creationist: "Given that Eve was only created after god
saw that Adam needed a partner, were Adam's genitals retro-fitted?"
