Since the Earth's creation, its population of living organisms have evolved and become more adaptive and advanced. It has had billions on billions of years to do this but how much time does it have left before it is wiped from the universe?
A very interesting question, but, to even begin to guess at an answer, other questions have to be asked:
First, how do you know that the earth is billions of years old?
Second, how do you know that that "organisms have evolved and become more adaptive and advanced"?
There’s less evidence than you think - for both those supposed facts.
Drosophila, I feel this is not the site for creationist nonsense.
Please keep your responses polite as Drosophila is entitled to his/her views, however wrong they are. Note that this is the final say on the subject in this thread and any further discussion on the subject of creationism will be removed.
Thank you Jonathan
Lewis, I have not mentioned anything about creation in this discussion, but can partly empathise with your reaction.
It is difficult not to allow our core beliefs and personal biases to affect our science; but my scepticism about Evolution, and the billions of years required for it to be even remotely likely, has nothing to do with my beliefs. (I used to think that God somehow caused Evolution, and was furious to have that belief challenged!)
One of my university lecturers was a humanist and agnostic, yet was extremely sceptical about Evolution, on scientific grounds. I admire his courage – no doubt he got some abuse and mockery from his colleagues too.
Scientists are supposed to consider nothing in the natural world as completely proven; and be willing to discard the most dearly held theory if further evidence throws serious doubt on it. However, in practice this seldom happens - especially in the case of Evolution. Anyone who refuses to toe the party line is considered a “heretic” and often subject to personal attacks, when what is wanted is a reasonable discussion of the science. (I admit this is annoying - I'm only human too!)
I will do my best to confine any future discussion on topics like “What kind of spider is this?” (I hope, Jonathan, you will allow this present comment to stand just this once).
If anyone wants to discuss these things further you are welcome to contact me privately.
I am a little humbled by your beautiful post. Maybe it's I that should stick to misidentifying Steatoda.
the earth, as in the earth as a celestial body we assume will survive until the sun eventually turns into a red giant engulfing the inner planets but as in the biological earth with the organisms and life that we recognise today its harder to say for a whole host of reasons, not limited to humans effect on the planet.
I do agree that the earth will be destroyed through fire
But the timing is anyone's guess.
However, on your second point, there does seem to be evidence that the genome of most or all eukaryotes (anything other than bacteria and such like) is gradually deteriorating. That includes humans. I read that in some societies there is now concern that marriage of first cousins is resulting in children with an unacceptable load of inherited defects. There is even talk that it should be made illegal because of this risk. There is a similar problem in controlled breeding of endangered species in zoos etc - great care must be taken to only breed animals that are not very closely related. There was also a TV programme about Crufts - the problems of inbreeding in pedigree dogs. A mutt is often far healthier than a prize poodle!
If this deterioration continues, then in theory we might become extinct before the sun reaches the Red Giant stage - if that is the eventual scenario.
