How Evolution REALLY Works, Part II

Natural Selection prevents deleterious mutations from spreading throughout a population while fostering the spread of beneficial mutations.

One can get populations to do many things with this simulator. Just remember, if your parameters are not realistic, your solution will not represent reality.

Predator evolution is simulated by scaling the populations mean survival probability back to the attrition rate. Example. If the Attrition rate is 0.9 and every member of the population has a number of beneficial mutations then the mean probability of death may be 0.8. If the predators were allowed to evolve (as they would in nature) that would scale the mean death probability back to 0.9. This is known as the Red Queen Hypothesis. The organisms have to keep evolving just to stand still. Without predator evolution enough beneficial mutations can pile up to lower the death probability to 0 (or nearly so). This would stop selection as every member would live to mate.

Error: I stated that without selection, evolution stops. This is not entirely true. Genetic drift operates in the absence of selection. It is one mechanism by which neutral mutations can become fixed in a populations.

Think about it.

I was going to call you out on forgetting genetic drift but you included it in the discription. Can I get matlab for free?

@benpipercom "What you are doing is like mixing different colors of paint and creating new colors, but you never end up with anything other than paint."

Yeah, strange, but mixing different life and creating new life never ends up anything other than life....

You seem to willingly not understand the concept of this simulation, with all its simplicity...

Dont worry dude! Evolution will take care of those dumb creationists.

cdk007, your video is self-contradictory. Genetic populations are as stable as they are because of error-correcting mechanisms in sequencing and redundancies in the genome. Also, the simulator is simulating cross-breeding, *not* Darwinian evolution. What you are doing is like mixing different colors of paint and creating new colors, but you never end up with anything other than paint.

For those who think that because he programmed it himself means that he could have tweaked the parameters to his favour, simply learn MATLAB and look at his code.

@achilles197474 Dude we evolved in Africa where people were black, now there are white people and that just because of the difference in light and vitamin D production in the skin, we have wisdom teeth that are too big for our mouths now because of the discovery of fire.

we will evolve further because our fat kids sit in front of the TV rather than playing.

But what make me laugh about creationists is how do they explain

1) Neanderthals

2) Dinosaurs

3) Heisenberg uncertainty principle

@ianman6 What I mean, is, that like, a tiger cant just Slam down your door, walk upstairs and kill you, then travel back out of your town, and into the wild. Or, how you can shoot an animal, but it can't shoot you. or how you can climb a ladder to safety, but only humans can follow. You know what I mean?
