gluadys said:Because the necessary mutations did not occur in those species. Or if they did, they were not selected for preservation.
i was taught in biology that mutations are usually harmful and rarely if ever passed on.
For the most part evolution does not require hybrids to occur at all. So why would you expect to see them?
so one day, we should wake up and just expect to see a different species or an alteration to an existing one? please clarify this.
That's fine since it is not completely uniform and has never stopped.
if people existed in different stages, why don't we still see some of those stages walking around? are you telling me that the entire population evolved into the same type of man all around at the same time and we have no other types walking around?
Since there is no goal for evolution to meet the concept of "fully evolved" is nonsense. You have to have something in mind to measure evolution against to say it is "fully" evolved and there is no such standard.
i didn't get my idea across as clearly as i wanted to. what i was trying to say way. evolved as we are now. why did the process stop now that we can understand it and speculate it, there is no visible proof of it.
It didn't. You keep trying to put the evolutionary process in the wrong order. As best I can figure out you think it works like this:
species perceives future need->species changes to meet that need.
But that is not the way it works. Here is the proper order.
A mutation occurs which generates a variation in a species' characteristics->as a consequence the members of the species which inherit the variation have more surviving progeny than those without the new variation.
that is the way it's taught in public school. i've never seen or heard of a two headed snake have other two headed snakes or 5 legged sheep give birth to other sheep with 5 legs. why is that? can you answer without using a human attribute?
So evolution did not "know" we needed eyes. A mutation occurred in one of our far distant ancestors which caused a chemical change in some cells that made them photosensitive. Members of the species with this variation were able to survive and reproduce more frequently than those without. Over several generations, the variation became more common, and eventually universal in the species.
the way evolution is explained is by using characteristics that are attributed to living beings. words such as kept, knew, changed, etc. to me that attributes a life like characteristic to a supposedly non living, non biased force.
Additional mutations selected over the generations added new features and improvements to the primitive eye-spot until the eye we are familiar with in humans emerged.
so what came first, the retina or the cornia, or the optic nerve, etc. how did these mutations "know" that it would be beneficial. the first eye couldn't possibly have worked that good, so why keep it?
Ah, so you don't actually know what the 2LOT is. That explains why it puzzles you.
no, it's obvious that you don't know.
"Simply put, this universal law of science says that all systems, if left to themselves, move from a state of order to disorder... So, a better example might be that pile of bricks in my backyard. If no one touches if for the next 1000 years they will eventually wear away. That is, if left alone they will not move themselves and form a wall. " - creationdefense.org/113.htm
C'mon, you want to be spoonfed the whole history of the universe in a forum post? Head to the library and start reading.
no, but i would like to know where it all came from in the first place. please share if you know. and lets just asume that there was a cosmic egg, where was it? it wasn't floating in space because if i recall the big bang gave birth to space... please correct me if i'm wrong.
That is the question scientists in the field of abiogenesis are researching. Stick around and they may find the answer in your lifetime.
i seriously doubt it. unless God plans to show up and tell them that He did it.
Because the conditions in which life first arose no longer exist on earth today.
well, lets just recreate those conditions.... wait, someone tried that and failed. yes, he managed to create amonia and some other lethal chemicals, but none that would give rise to life as we know it.
A lot of macro-evolution would not show up in pictures. For example, a major change in the physiology of digestion which permitted a change in diet from fruit to bread.
so i assume since you've probably never seen it, what's the difference between taking that based on faith and believing in God as the creator? i don't see one.
Better to go to the scientific studies on speciation. I can give you a list of 50 (out of thousands) to research.
thanks i would appreciate that.
No, the intelligence is need to replicate the conditions in nature in which evolution occurs. No manipulation of DNA is required.
ah, but they did manipulate the DNA to get the flies to produce 4 wings, which didn't work as i stated before and they died quicker too. are you really trying to convince me that nature's accidents are better than mans best informed attempt at recreating the conditions?
Also some experiments are done in natural conditions. So no manipulation of the conditions is needed either. No human manipulated the climate changes that led to evolution in the Galapagos finches in the last 20 years.
there have been humans there for the last 20 years. just by people being there, that changes the environment. it's not possible to study something in it's natural environment if it can interact with you on any level.
No, evolution has nothing to do with improvment. It is just a survival mechanism. Fit into your environment better and your progeny are more likely to survive. At least until the environmental conditions change.
true, it has to do with survival, since when are beneficial mutations passed on in mass? prophets for example. there has not been one prophecy in the Bible proven to be wrong... if so, please tell me which one and with references... so why isn't the ability to predict future events passed on? that would seem very beneficial.
Possibly trees were becoming rarer as jungles gave way to savannahs.
from what i see, monkeys don't spend the majority of their time walking upright. even the one's in india and other countries that live in the city with people and have done so for years. they still look and act like monkeys.
Possibly because we needed a cooling mechanism such as sweat to release excess heat after heavy exertion, like chasing down game, or escaping predators. Or, some theorize, that for a while our ancestors were aquatic and lost their body hair as an adaptation to spending many hours in the water. I don't give much creedance to the latter hypothesis, but it has been seriously proposed.
so wait, the other monkies decided that they didn't need to regulate body temp? they seem just fine to me... i agree, that sounds dumb about being aquatic... i thought we came out of the water, so why go back in?
Possibly because we began using technology and didn't need greater strength to compete.
monkies use technology. not as advanced as ours, but simple technology. and FYI we shed all of those characteristics before we started using more advanced technology.
That is why science does not rely on opinion but seeks out the facts. A lot of science is counter-intuitive. It's different from what we expected.
they certainly don't seem to rely on fact.
