It doesn't matter wether you right or wrong ? just try to sum up your ideas , you can say it in one sentence , but it will be great if you are more generous with words !!
feel free to share your knowledge , some may find what you say more helpful than academic books !
I see what you mean Reg ; so many non-religious scientist on a video I watched on youtube say that if there is a ''god'' , it cannot be the same god of nowadays religions or all the previous religions...they went further (joking) and said that aliens helped by providing the right conditions for The Primordial Soup .
That actually has (at least) three totally different and plausible interpretations:
Evolution of our Universe?
Evolution of our Solar System?
Evolution of life on Earth?
Presumably you referring to the last, so I'll give it a shot (without using google or reading other responses!):
It starts with Abiogenesis, which is the study of how biological life started. Still a bit in it's infancy, there is good evidence of how the available molecules would arrange themselves to form the building blocks of life. Life as we know it is based on carbon, which is the most versatile (in forming chemical bonds) molecule and a natural building block. It would attract sugars and proteins, and eventually end up forming DNA. The DNA then attracted lipids to form a protective shell, thus forming the first proto-cells.
These carbon based cells needed carbon to replicate, which incidentally was quite common on the young earth due to volcaning activity. This process (via photysynthesis) released massive amounts of oxygen into the atmosphere, a molecule which has been shown to turbo-charge evolution of life. Cells which could "cooperate" with other cells had a higher probability of successful reproduction, and the march towards multi cellular life started.
After this initial phase, there is very much repetition over a theme. As DNA replicates, there are always some small mistakes (mutations), and (more importantly) certain offspring may have different combination of alleles switched on and off creating genetic drift. As conditions changed throughout the Earth's history, these first multicelluar globs evolved into basic oceanic lifeforms, from which subsequent life can trace its roots.
Certain traits proved to be better adapted to the environment and carriers of these traits would reprocreate more successfully than the average population. The less well adapted variants would eventually die out, and the highly adapted ones would continue to evolve, etc.
I can probably write a lot more, but I think that should probably contain enough schoolboy mistakes for any evolutionary science literate person to get a good laugh. :)
Mutations should not be considered “mistakes”. If cells are constantly dividing and replicating (passing on DNA) then mutations creep in. So if it happens once in a billion (that is a very small number on the genome level) a sequence in the DNA chain is altered. This may result in the mutation getting naturally selected or rejected depending on whether or not it is beneficial to the life (survival) of the organism. That decision is based upon the environment where the organism is living. It is really only this decision that is important as Evolution is only concerned with survival NOW in order to pass on its genetic code. Another way of looking at it is that Evolution has no long term goals.
One thing to bear in mind (sorry for repetition) and is a great one to hit the fundamentalists with is that Evoultion does not explain how life on Earth began. It has nothing to do with it. I have often heard them say “But the Theory of Evolution does not explain how life started”. No it does not is my reply because that is not what it is about. The fact that fire heats water does not explain why water freezes. It only seeks to explain how life evolved after it got started.
It can be a difficult idea to see clearly because it is based on changes made over time – usually a very long period of time. We generally cannot imagine what 100,000 years is like but life on Earth began over 500 million years ago. I have a few video on my page about evolution. I am not a Fronkey hunter for nothing you know !!!
Thanks for correcting me.
I think I grasp the fundamentals of the concept, but yet oh so much to learn about it before having even the right to hold any objection to it, if I ever would.
I actually saw the last video linked before and left a statement which should have been a question: Couldn't her claim be contradicted by punctuated equilibrium?
