The argument from poor design
is one reason I'm an athiest. I've questioned the quality of design in a couple of threads. Adam picked me up on it a while ago, and in the Why evolution is clear to me
thread Ikester asked me:
Why is it designed badly?
Good question. I have no idea why, if it was designed, so much of the natural world appears designed badly.
The following are just a few observations that make deliberate design questionable:Strawberry Naevus
My daughter has one of these, luckily nowhere obvious and much smaller than the images in the link. A strawberry naevus is generally symptomless and disappears without treatment in due course.Varicose veins
seem like a strange and pointless design feature to introduce to 30% of all human adults
The human GULO gene
, discussed at length in this very forum, but sadly with no coherent design explanation.Irukanji jellyfish
stings induce muscle cramps in the arms and legs, severe pain in the back and kidneys, and a burning sensation of the skin and face, headaches, nausea, restlessness, sweating, vomiting, high heart rate and blood pressure. Occasionally they are fatal.
The irukanji is almost invisible to us in the water. Most people who get stung never see the jellyfish. Some animals, wasps (which are also generally not lethal) for example, have very obvious colouring which says "keep clear". The absolute opposite is true of the irukanji. What a fiendish piece of design this is!
I could go on - the pandas' thumbs, the human appendix and so on are all mentioned in the wiki link above.
There seems to be no design explanation for this other than we are part of a fallen world, or God's whim, or some other such hand waving.
