Evolution Again!

[_Ceeboo]

I have until tomorrow to finalize the Team-Ceeboo jersey order!

Who else needs one? (please send me your size as well)

Hello friends!

I invite any/all to pull up a chair and shoot the s*** with Ceeboo

(Please don't feel you are required to spend your time in posting to teach me anything! No need to offer me any books to read! Participation in not mandatory, it is purely OPTIONAL!) :smile

Another mind-bender (in my opinion)

Sexual Reproduction and Mitosis (Cell splitting for reproduction):

So how did this all work:

One multi-cellular animal grew an appendage (after millions of years) then decided to insert it into a fold of another mult-celluar animal that didn't have this appendage. just because, or to merely see what would happen?

How could perfectly matched male and female sexual organs evolve in separate individuals of a species?

The random mutations and natural selection of one gender would have to know what random mutations and natural selection was taking place for the other gender (All with no "intelligence" involved)

What about cell mitosis?
This an all or none event, yes?
Splitting of cells cannot evolve in steps (.0001, .0002. etc). It's a split of no-split deal, yes?

What about copulation? (All or none event, yes?)
What about the fertilization of sperm and female egg? (All or none event, yes?)

Anybody want to share their thoughts/perspectives/opinions?

Peace,
Ceeboo

Large. I like mine baggy.

XL. It's ... uh ... for a friend.

Quasi and Bret too!

We almost have enough people to start considering practice times and electing a team captain!

Quasi and Bret too!

Yup! And I am currently working on a dissertation demonstrating how Intelligent Design 'splains why whales have pelvises and vestigial legs. It may take a while because it involves string theory and parallel universes, neither of which I understand.

If Ceeboo isn't elected team captain, I'm out.

Have you seen pictures of these "vestigial hind legs" that came from my beloved racoon-like furry quadruped? Do they look like former rear leg bones to you?

Okay, so these "vestigial leg" bones are completely internal (No part of them have an external remnant whatsoever). So the legs shrank, bent themselves into an "L", fused the knee joint, and moved themselves way inside the body of a whale.

Also, why are there several muscles attached to these "vestigial leg bones". Could it be that they have a modern purpose in whales and they are not a remnant of an evolutionary past at all?

Is it possible that they are a whale birthing apparatus?

Possible?

Maybe?

If Ceeboo isn't elected team captain, I'm out.

Ohhhhh No!

I can not put the team together AND be its captain!

We will have to vote!

Peace,
Ceeboo

Just have to point out that many vestigial body parts have a purpose (as it were). It is not part of the meaning of vestigial that they be useless.
Vetigial wings in some birds help with balance when running for example.
What matters is that these body parts have become "exapted" for other purposes than the common "original" purpose.

As for whales we can trace back and see how the leg bones came to be vestigial.

So I assume you're not on Team-Ceeboo? (No jersey needed?)

Well, I guess you're going to have to pick from DCP, Liz or Kish.

(I heard their team colors are pretty dull)

The details of the evolution of sex and mitosis are open questions as far as I know. Did you think there is no more science to work out in evolutionary biology? Did you think all the details have to be in before we know that evolution occured? (It did as we already know for countless other reasons).
Your suggestions above are just reworkings of the idea of irreducible complexity (all or nothing). We know from past experience that supposedly irreducibly complex structures eventually give way to plausible evolutionary pathways. The lesson is that irreducible complexity is just a failure of imagination (I can't see how it was done so it wasn't!).

There are things to learn though:

Damn. Your raccoon pic was better than mine. {shakes fist}

The pic seems to have been taken down again.
