Just to get a functioning mammal, you have to have a bunch of mutations that are simultaneous and coordinated. You need an articulated skeletal structure, a musculature, a nervous system capable of moving those muscles, a circulatory system to nourish tissue, a pulmonary system to oxygenate the blood, etc. These changes have to occur at the right pace, and be calibrated for proper interaction. Randomness is too blunt an instrument........
Ah, now I see what you're driving at. I think. You are assuming that you throw all the chemicals up in the air and BINGO! by magic they just happen to fall into place to make a mammal- -one time out of the quadrillions of times you try the experiment. May I point out this is not what theory says?
To get that mammal you are talking about you start with a reptile- -which already has "an articulated skeletal structure, a musculature, a nervous system capable of moving those muscles, a circulatory system to nourish tissue, a pulmonary system to oxygenate the blood, etc." You don't need to create all that from scratch. It's there; you need to modify it.
And to get that reptile, you started with an amphibian, and to get that amphibian, .....
Come on, Neo, straw man arguments don't cut it. |
