Yes I do understand.
Allow me to demonstrate his in my own words for your review. The body has many cells and divide to reproduce, here we see that somehow those thousands of cells have collected together to form a larger (more or less) self-contained single unit - the human body ( or animals body -etc.). These single cells have internal instructions and together they make up the total 'mass' of the body. These cells are involved in a network system that is inter-connected with other cells that work together to form the sinular purpose of that body. (or purposes). The oganization is supervised by other factors but the other factors are still part of that singular system of operation - the total body. The larger complexity.
The cells formulate as different organs within the body that perform diffeent purposes for the networking system of the body. Cordinated by a communicational network of electronic like signals or energy, nerves, chemicals, and even actural thoughts. Changes and growth takes place relative to the totality of the body and partly due to cell replacements and that can be evidenced as age and biologically timed.
In reproduction from generation to generation most of the system is reproduced in order and is effected as that total organization. The lungs are in the same place as in the piror generation. Not much in the way of randomness happens because the next person does not have a heart where the big toe belongs. However the nose might be bigger or the legs longer. Or shorter. But it is still a nose and it is where it should be located. The nose of a dolphin does not operate just like the nose of a dog nor is it in the same location. That is a "big jump" in change.
But possible. The nose (gills) of a fish are designed for one particular environment - water. The nose of a dog is designed for it's enviroment, as well as with smelling senses to detect food and so forth. The dolphin nose is designed to breath air from above the surface but also designed not to chock on the water by strong exhale. The dolphin has no reason to sniff around at trees for scents. Therefore. If the doggie Dolphin did change is is because it was adapting to a new environment and somehow the genes would have to sense that such a change was urgent or predicted to be urgent for the sake of the survival of future generations, hardly a random accident. But it is also logical that they always lived along the coast and took advantage of interchangable environments. Perhaps at one time venturing onto beaches to reproduce like seals but later evolved ways to do that underwater and so they no longer needed feet (or even lippers). We have lizards that share two environements of land and sea. And off Caifornia we have snakes that live in the ocean.
Animals that enjoy multi environments is not all that uncommon. The african catfish can walk on land and if one pond dries up it simply walks over to another pond. Other catfish cannot do that. But the point is that environments influence the changes if such transfomations are happening. However environments do not directly control growth and so I did not agree with Gallo the the womb is an environment that can cause changes as an infant is transformed from one 'shape' of creature into another 'shape'. Starting off as a microscopic sized being. One idea in evolution is that single cells evolved into higher froms of animals but the fact is that they "collected in units" to make up the larger identity.
A single cell reproducing more of it's own to form a community of cells that then operate as a more complex system as a dog, or what have you.
Like our culture as a unit would have reproduced more people until we had lots of people who then had different tasks for that single-unit culture - plumbers, brick layers, computer operaters, chemists, scientists, lawyers, doctors, and housewives. Each representing an organ for the total system of united operation. (as a anology). Was a plumber effected by random accidents or because he filled a need that became evident as the total environmental culture advanced? Now a tree has no heart to pump sap up and down from root to outer branch, that is controled by environemental temperatures. Where as a human has an internal temperature our "sap" remains warm blooded. So we need a pump to keep the cirulation going. (and a plumber would be handy if you get a heart attack). point being - we have lots of factors to concider and options to study to formulate our opinons about evolution or adaptation. Like comparing social science facts with biological facts and seeing if some common denominator sheds any light on our understanding about life, growth, and change. And to question 'are environments also the products of evoluton'? Or is evolution the side effect of the environment? Or do both influence the other? Are both the same thing? Not just as an abstract philosophy or 'belief' but as something realistic and logical.
We would need to comprehend how randomness can effect logical order, that is the basic key to the so-called mystery. logical order would mean that eliminaiton of pointless directions would happen until only the most workable directions survived.
Now about the sex genes you talked about. It is true that to insure connection a lot of them are produced and it would seem by random chance only one of many would join one of many to produce the conception. And based on that we assume that one of many potentials would be passed on by that random chance. The math is the math but the theory would be hard to test. To do so you would have to use the same female egg and have different sperms connect with it to see if they all came out as different individuals or as clones. Being you could not re-use the egg which is also part of the growth process the theory of diversity cannot be factually tested under lab conditions. Otherwise you can speculate the chances favor potential diversity.
Now the combination is in fact a new individual identity unlike any other but that does not prove that if another sperm had reached the egg that it would be unlike the one that did - result wise. As they are produced under the same conditions from the same source at the same time. And also, this is not proof that the reproduction of one couple could change the whole speices. Anology - it rains form a cloud and the water forms fozen particles of snow, each flake has it's own design like no other flake in history. However that does not effect the over all image of snow as snow, nor does that cause any kind of evolution in the nature or make up that process. If snow is always snow then people are always people no matter what individual designs might be noticed among them.
