There might come a day when humans may have to consider engineering specific traits in their descendants in order to survive alien environments.One such alien environment that might need adapting to is living underwater.Several species of land animals on our planet have even gone aquatic at some time in the past but they all have something we lack, er I should say they all lack something we have, pores.
If humans were to try and live continuously in water we would bloat and die because we aren't water tight but there is one person alive who does lack pores... nipples and most of his teeth as well but that's beside the point [link].It is possible that this trait could be engineered so that a race of people could become semi aquatic.
This is where it gets weird and might very well not work.
Removed by c section prematurely, the babies are connected by umbilicus to a device which simulates a human placenta, sort of a miniature dialysis machine/ intravenous oxygenator weight belt for buoyancy control.If a baby never takes their first breath, do they need to? Perhaps over time our appendixes may regrow a way to extract oxygen from the water without assistance.
Until that time though I think that some of pore-less buddies' DNA should be saved if for no other reason than to discover how it is even possible.-- 2 fries shy of a happy meal, Jun 02 2011 Chen Lun http://english.epoc...s/5-10-8/32923.html [2 fries shy of a happy meal, Jun 02 2011] Song Sheng http://www.telegrap...-14-months-old.html [rcarty, Jun 02 2011] Aquatic ape hypothesis http://en.wikipedia...atic_ape_hypothesis [ldischler, Jun 02 2011] Holy friggin crap [rcarty].

Osmotically, it should be fine.-- MaxwellBuchanan, Jun 02 2011 One theory of human evolution has us going through a recent aquatic phase.-- ldischler, Jun 02 2011 That's up there with the theory of us having evolved through a Middle-Earth phase.-- MaxwellBuchanan, Jun 02 2011 Well I do kind of have extra-hairy toes...
[ldischler] there is a very good TED talk by Elaine Morgan on the aquatic ape theory.-- 2 fries shy of a happy meal, Jun 03 2011 A good Idea, and useful too. Because species should differentiate, one spices becoming a number of related species. As well as species evolving over time, there are extinctions and mass extinctions. The more different types of homo sapience that there, in the widest range of habitats, the grater are the chances of long term survival.-- j paul, Jun 03 2011 I have a friend with webbed-feet.-- theleopard, Jun 03 2011 The first one could be named Ethel.-- bungston, Jun 03 2011 random, halfbakery
