I would suggest you are simply not listening hard enough.

(b)I think that Darwin was correct in most of his assertions and that evolution must apply to human beings as well as any other animal. Do you believe this? If so, then I return to one of my earlier questions Why are we here now in what we like to call early twentyfirst century why not at some other time? I do not believe that life as such is just a one ...[text shortened]... ally lightened as our need for light and heat increased. Do you think these are possibilities?
Yes, Darwin was very correct in most things he said, eventho he didnt have such a great understanding of heredity of DNA as we have today. Also his theory of natural selection is not the only mechanism that supports evolution.
Yes, i believe evolution was the reason for every life that it is how it is today. This includes humans and animals, but also plants, bacteria, etc. I even believe that all life evolved from one common ancestor. (please keep in mind that this happened in a Hudge timeframe).
"Why are we here now in what we like to call early twentyfirst century why not at some other time? I do not believe that life as such is just a one off occurance."
im not sure what "one off occurance" means, let me know if my answer does not cover it.
We are here now due to pure coincidence. Somewhere around 3.5 billion years ago life on earth originated. From then: Evolution as mechanism for more and more different and complex life. Somewhere around 60 million years ago the first ancestral primates (primate:
highly developed mammalian) originated. Then about 5-7 million years ago the first humans originated from chimpanzees. Today: You and me are living🙂
Why? Theres not really an answer to that, this didnt happen because it was a set out path. Its pure coincidence.
"I dont see that it really matters whether you call our being a soul or something other. I am not suggesting that it can be proved but it is what I reason to be most likely scenario for life."
our being? as human? I think alot of people like to believe that we have some kind of 'soul', something extra then any other life (animals, plants, bacteria...etc). Because we are very intelligent, we can think about why we are here, and wonder how it happened. Animals and other life dont do that, they just 'are'.
But i think this soul is a made up thing. There are alot of things that we dont understand, and people like to fill the questions up with answers they feel comfortable about, eventho theres no proof of it.
We are intelligent because our brain is highly developed, our brain is made up from molecules, just as everything else. We die: our brain stops functioning (as the rest of our body) and our molecules 'recycle' (get burnt up or rott away). We, as a human, are no more. Just the atoms that once made us are still around there, but with totaly different functions.
"I bow to your superior knowledge on giraffes etc and I am sure that you are correct in what you say."
haha thanks:p i wouldnt call it superior tho, giraffe is just a good example for natural selection🙂
"You state that you cannot pass any experiences from life into DNA I am not so sure because numerous species have altered in time to adjust to altering situations that they faced either for food or survival or both."
This is exacly what Darwins natural selection covers. Survival of the fittest. The better adapted survive, others might die, or produce way less offspring which eventualy will result in extinction.
I can use a part of Darwins voyage on the HMS Beagle (started in december 1831, Darwin was 22 years old) as a good example. (it is the year of darwin after all😉 ).
At this voyage they spent some time on the Galápos Islands were Darwin observed finches.
There are different spieces of finches on these islands that evolved from one common finch ancestor species on one island. When the competition for food (insects) was high certain finches started eating seeds. Finches with a bigger, stronger beak could eat more seeds and produce more offspring. Also when finches would migrate to another island, geographic isolation would occur and eventualy these finches became different spieces since they cannot produce fertile offspring with the original finches anymore.
(The Galápos Islands have a total of 14 species of closely related finches, some are only on a single island. There are seed eaters, insect eaters and even tool-using insect eaters (i do not know if the insect eaters were the first finches, used it as an example). Again, think in many millions of years).
"When homo erectus stood up in Africa he was doing just that was he not?"
I dont know, maybe we are a product of a mutation that was in our favour..dunno.
"and as we(human beings) spread north and south our skins gradually lightened as our need for light and heat increased. Do you think these are possibilities?"
Hmm, no. The lightning of the skin of these spreading humans did not happen because we needed more light or heat. That has nothing to do with skin colour (not in that way).
A dark skin colour is caused by alot of melanin, the pigment in the skin. This pigment protects the skin against high sun concentrations.
Here is what wiki explains in short (i know, wiki aint a great scientific source, but they do explain it easy..):
originaly we had skins with less melanin, like apes. After we losed our hairy bodys (most likely to be able to cool down, sweat better) we started getting more melanin to protect us from the sunlight.
When migrating to less sunny areas a supply of Vitamin D became a problem and we started to get a lighter skin colour agian. Diet and sexual selection may have helped here.

How do Salmon know how to get back exactly to the place their parents came from even though their parents died before they were born?
I thought the info was stored in DNA.
Anyone know?
P-
Salmon get born in the rivers thier parents got born in. They already are in this place thier parents came from.
Then they take off to the sea, feed and such, and after a while return again, to the exact same place they were born.
Its quite interesting how they can do this, studys have showed it has to do with the ablility of salmon to imprint odors from thier home streams (when they are young). When homing the adult salmon uses these memories to find its path home.
i suggest this study if you would like to know more about it:

Why is this? O_o
with a promise you can assure someone that you will fulfill a certain action in the future when you can not at that time. It can also make a bond between ppl stronger.
and could you please fix your Enter key, it keeps making 2 enters when u hit it once;(
"Will you... ?" Husband, "Yes." Wife, "Promise?" Necessity of promises redefines relationships to an iffy proposition and less trusting level.

No it doesnt, not in general. Sometimes a promise is needed, when u cant offer something at the very moment, cause u might not have brought it with you. You promise to take it with you next time. Next time, you took the item (lets say its an item, this is an example..), because u care for the certain person you were taking it for, and remembered.
This other certain person will be happy u took the item, you kept your promise; the bond between you and the other person grew stronger!
In your example the wife is asking for a promise, this is indeed like she doesnt trust her husband.
But like i tryd to explain with my example: A promise is not necesserily a bad thing.
Also:
Care to explain to me why u fancy double enters so much?

Reading your posts is annoying because of these cut-in-half lines.
(And because of your use of 'proper' english words which forces me to google-translate half your lines😛 )

was just wondering what reason u had to make these silly double enters. Then i was trying to change your mind by giving arguments. But i guess ur not changing the way you post lol:p

I think the whole world learned to type like i do, so you are still the awkward, silly typing one,
so you change!😠

There might be solutions like that for Internet Explorer or other browsers, too.
