Nothing that contradicts your theory is going to influence you. I will leave you with this.
DNA determines what an organism will become. In order for an organism to evolve, it must receive new information. There is no mechanism to determine what that new information should be. If it is incremental by pure chance, then a male and female must evolve at the same time and in the same physical location. You also need many more than one pair. Inbreeding is catastrophic as those trying to recover near extinct creatures will testify. If anything is genetically corrupted, the organism dies. Since this is entirely random, the organism may never produce a suitable mutation. The evolved creature is still born. This must be repeated countless times in order to produce a viable breeding pair. I know something about encryption. Producing a warm blooded mammal from a reptile is akin to encrypting the Encyclopaedia Britannica and producing the complete works of Shakespeare.
How did blood come to be? How did blood know that it needed a vessel? Arteries and veins had to evolve at the same time as blood. And a remarkably robust pumping system that self adjusts flow rate to suit the organism's needs? Plus a sophisticated temperature control system. That's before we get into oxygen and CO2 exchange systems, built in defences against bacteria and viral infections and the amazing self repair ability of living organisms. We know how vulnerable people are if their immune system is compromised. How many billions of creatures died before evolution coughed up the immune system? And everything goes back to zero if an evolved creature dies. The whole process starts again. Nope. Way too far fetched for me.
ouch....your using ray comfort...thats a new low I havn't seen in ages.
simple answer, none of the first of anything had modern forms of any of that. Sexes would have evolved early on and formed from the same species, probably from simple dimorphism in it's life cycle or such. It's not like the first male baboon and female Baboon suddenly appeared randomly on the planet, everything in evolution had a parent that was nearly exactly like itself.
As for warmblooded to cold blooded, we know it happened twice so can't be all that hard, reptiles that have the benefit of regulating their temperatures a bit better would have benefits, it's not like they went cold turkey from cold blooded to warm blooded, it's something that would have happened over time, all of these happened over time. We can see in existing animals alot of the changes for blood and such along with immune systems. Simple animals have simple versions of it, it's that old saying, what good is half a eye? it's better then no eye, what good is half a heart? Two sections is better then one and so on.
And no way for new information....been waiting days for this argument, thought it would have come sooner, you guys really disapoint some times. YOU have 50+ new 'information' in your DNA that wasn't there from your parents, we all do, errors in replication cause mutations where chomosonal pairs are missing, or added, parts of your DNA might be flipped and so on, this happens every time a kid is born. Most of what is in you will be neutral, rarly will be beneficial. What about harmful mutations, they generally don't last long enough to be born.
