I like to keep things simple. I can get deep and I’ve been down that road but lets stick to some minor probing. Do you embrace as a fact (not idea) that all complex life forms came from one cell that of itself has an improbable origin.? Now even if we take that leap. We then have to take the leap that simultaneously or at least quasi simultaneously duplicate cells were “evolving” (male , female). I also want to touch on something you got heavy into.
If giraffes experienced too much competition for food, so that they had to stretch their necks even higher to reach the top most leaves of trees, then, ultimately, if all generations stretched their necks, the necks of descendents would get longer. It’s sometimes called Lamarckianism. Question: would parents who who work out with weights everyday automatically pass the development of large muscles to their children?
Lets take it even further. Would having a leg amputated cause a man to have legless children.? I mean, even if every father in every generation was so unfortunate as to have his leg amputated, would the children be legless? The parents DNA cells are not effected by such things but the giraffe and almost every other species is. This is a simple illustration of what the core of the evolutionary process is. We don’t even need to go to God yet.
Are you trolling?
It would seem that the only way to be this specifically wrong were if it was deliberate.
Lamarkianism is an almost-entirely discredited theory. There have been some Lamarkian-esque things that have shown up recently in the field of epigenetics, but they are largely systemic effects due to the methylation and chromatin restructuring (I don’t think this is where you were going, so I’ll stop here).
The example of the giraffes stretching their necks out is exactly the type of thing that would** not** transfer genetically…
Lamarkianism is NOT evolution. Since you like to keep things simple, let me set out the differences directly:
Lamarkianism: A giraffe is born. This giraffe stretches its neck to reach the leaves, and this stretching effort is passed on to its children. This doesn’t happen.
Evolution: Multiple giraffes are born, some are born with genes that will make them have longer necks than others (much like humans come in a variety of heights, even among siblings). The ones who have the longer necks can reach more food, and are more likely to survive long enough to pass on their genes to their kids. When these tall giraffes have kids, the taller ones of those kids will reach even more food, and thus will be more likely to have taller children.
Now, the longer the neck works, the more the heart has to work to pump the blood. At some point, the amount of food the giraffe could reach by being a little taller is not worth the extra heart trouble. At this point, the plateau is reached, and the necks stop getting longer.
Regarding the origins of life, from a single cell to multi-cell organisms, yes. I agree it is incredibly improbable. In fact it’s so improbable that it would probably have taken an entire planet of single cells billions of years for it to start happening.
Caution, math ahead:
Fortunately, if we assume that a cell could divide 1,000 times a year (about 3 times a day), and that in the prehistoric oceans, there may have been 10^24 cells at any one time (there are about 10^13 in a human body, and about 10^10 humans on the planet, I made us 10% of the prehistoric biomass, a
very conservative estimate). Then if we give these cells a billion years to do their thing, we end up with 10^36, or 1,000,000,000,000,000,000,000,000,000,000,000,000 cell divisions. Thus the formation of good polycellular organisms is allowed to be improbable, since it had a lot of time to happen, and it really only had to happen once.
As far as me embracing it as a “fact.” my definition of “fact” and yours may be off. But for my definition, I do take it as that.
(my definition being the event that, given current evidence, has a significantly higher probability of actuality than any other proposed theory I am aware of).
