Sadly my server has dumped your original 'explain neoteny' posting.
However, my original response lives on for a few days more at least (courtesy

Gee, I wish you'd corrected me straight away. This was the time to explain
yourself and tell me evolution has no preset goal.
And I also said...

I hate to disappoint you but you can't learn evolutionary theory from a
dictionary. Behind all those names you love to loath there is meaning, Mark,
and we learn the meanings too.
I have never said evolution never results in an increase in complexity. I
have disputed firstly your criteria for measuring complexity and second that
evolution always result in an increase in complexity. It clearly does
not, e.g. a change in gene frequencies or the secondary degeneration of
structures in e.g. leeches which results in a more derived but less 'complex'

If you don't want me to take cheap shots don't set up such easy targets.

Oh thank you, I feel so much better having finally got it right...

I'm at a loss. Why is this so difficult to grasp?
Would you be prepared to admit that the hearing system of bats is more complex
than ours? Yet bats are clearly less intelligent.
How about the digestive system of ruminants? Wow, all those stomachs. Yet
even I can out-think a cow.
How about bacterial dna polymerases that can withstand heat up to 94'C. More
'advanced' than ours? No great thinkers there.
Viruses which knock out our immune systems? Are they less advanced than our
For someone who sets such store by the writings of SF authors you have
surprisingly little imagination.
