Author | Topic: Wombat Pouch | |||||||||||||||||||||||||||||||||||||||||||

Straggler writes: An animal that climbs trees with it's belly dragging across the surface of the tree arguably has much the same reasons for an inverted pouch as a burrowing animal. If you climb a tree you do have to get back down too. Have you ever seen a koala traverse downwards? Much more useful for a koala would be a sideways facing pouch. Why has nature not produced this? Even better would be a pouch that rotates at the flick of a switch. A gentle spin speed would be natures very own merry go round.

Why has nature not produced this?
Why hasn't the Intelligent Designer? Depends on whether you are an evolutionist or a creationist. I have left the question open for all to answer.

jar writes: There is no plan, no goal, no direction to evolution since we got past the very first simplest life forms. What we see in nature and all living critters is "just goodnuff to get by". Given that evolution works on the principle of "just goodnuff", it really doesn't matter that much which way the pouch faces. Nature however, operates in a symmetrical fashion, with pouches facing upwards or downwards. We don't find any pouches at a 30 or 45 degree slant which should be perfectly acceptable. Pouches fashioned so that they are 180 degrees opposed suggests that design has played a part.

Dr Adequate writes: In short, being asymmetric is difficult. So "given that evolution works on the principle of "just goodnuff"", asymmetry won't be produced without a very good reason, whereas symmetry is the lazy way of doing things and occurs by default. This all sounds very plausible initially but a little bit of investigation would have revealed to you that internally we are far from symmetrical. The heart, the colon, intestines, stomach, appendix, pancreas not to mention others are all asymmetric.

Theoderic writes: My point is that not only do you have no clue what symmetry and asymmetry mean in biology, you are also incapable of doing basic research about the subject before spouting off and showing your ignorance. Shame there is no block/ignore feature here.

Dr Adequate writes: Credit me with a little common knowledge. I know that, which is why I explicitly said "Genes affecting the exterior of the body are going to be symmetrical in their effect". Think of the colon. Internally it's asymmetric but it attaches to the rectum and the anus which appear symmetric externally. The birthing canal is similarly asymmetric internally but the pouch appears as symmetric externally. If you have ever written software code you will know that it is generally good practice to hide the gory implementation details behind a more structured and friendlier interface. You have unwittingly presented your strongest argument for design over blind chance. Well done!

Dr A writes: The mutation that gives fruit flies an extra pair of wings gives them an extra pair of wings. The mutation that gives an American Curl cat curly ears makes both ears curly. I'm not sure what point you're trying to make as we only have one anus, one mouth, etc not a pair.

Dr A writes: Big Al, to his credit, is a perfectly decent guy Thanks for the vote of confidence. I never expected any acknowledgement on these forums and with my measly 200 posts to your 11000 I had taken my rejection on the chin. I had infact, for the greater part, forsaken EVC. Don't worry though I'm not looking for a slap on the back. I will however continue to make my points, whatever those might be at the time. Still getting back to the subject, I should point out examples of cleft palate which can have environmental or genetic factors. If you view pictures of these defects you will see that a mutation in this area generally does not have a symmetrical outcome.

Dr A writes: So long as we're exchanging views about biology, then even if you're completely wrong (which you are) It is interesting to note that you and your crew/colleagues need to point out that I'm wrong repeatedly both on this topic and countless others that I have contributed to. I think your 11000 posts speaks volumes though. I mean who has the time to make 11000 posts on these forums. Even if I was wrong (which I'm not), who has the time to insist that I am time and time again. In your life you will be right about things and wrong about things but you are behaving like a corporate shill. I don't know if there is any financial incentive in this for you but clearly you're interested in maintaining a status quo. Edited by Big_Al35, : No reason given.

Ringo was simply complimenting me on my hard earned knowledge, so I offered him some words of encouragement to show him the way. I don't know what personal attacks you're talking about.

Dr A writes: If you are really too socially inept to realize the problem with your recent posts, then by all means let us omit that discussion and revert to the question of wombat symmetry. Are you suggesting that he was making some kind of back handed remark? Ahhhh so it's not me who initiated the snide remarks. Nor was it me who stooped to just plain name calling.
