In other words, can one feel pretty confident that the results of any lab will be accurate?

I dont mean some magic cure of ageing. But think about this. Time is infinite, and the very unit of life (at least the life we know) is based around DNA and the cell. Now from conception, we are essentially a single cell with a very very specific sequence of DNA which WILL create us (us without any experiences or memories). So if we have an infinite amount of time, eventually, the molecule DNA, and eventually the very sequence of DNA which will create us will be produced. It has to happen eventually. This would mean that the body we know now is going to be produced many many times over throughout time. I suppose it isn't exactly us, but it is as though we are living our lives over and over again, but each time with different experiences. Seem probable? What are your thoughts?

True/False?
A life cycle in an insect is usually the period of time that begins with the egg and ends with the adult (capable of reproduction). Some insects take just a few days to complete a life cycle. Others make take many years.

I used to think that our DNA was one long strand but then I realised that our chromosomes are seperate from each other therefore DNA could not be in one long strand. Can it?

Does each chromosome have one long strand or are there more?

I'm wondering what color light, or LED light, is least likely to disrupt your night vision. I know if you use a regular indecent flashlight in the dark it takes a few moments for you to get your eyes readjusted to the dark. What light is best suited for not screwing up your night vision when in use?

I heard something about a red LED wasn’t hard on the eyes…?

I'm not religious, but don't believe in Darwinian theory. I believe that evolution has to be use based somewhat along the lines of Lamark or perhaps Lysenko.

Can anyone explain this one: The Bee Orchid pollinates and breeds by attracting bees to it and does so by looking surprisingly like a bee. How is this possible, if mutations are random? The orchids mutations were assumably not conscious, and an orchid cannot know what a bee looks like.

Assuming the first mutation, which had the orchid start looking vaguely like a bee occurred randomly. Further mutations making the orchid look more like a bee through "genetic drift" must become even more so improbable if the orchid can't know what a bee looks like.

I don't think that random mutations result in evolution; it must be environmental factors that "COMPEL" the mutation.

Any comments.. sensible people only. no Christian lunatics please.

I get the academic interest in evolutionary biology, but would like to better be able to communicate why it's important to people generally (beyond the obvious example of antibiotic resistance in bacteria). What else does understanding evolutionary biology do for us?

This is a serious question.
Obviously the heart stopping and breathing stopping are quite significant indicators, but there are cases where both these occur but the person still recovers maybe 10 minutes later .

Ultimately does science yet have a hard and fast measure as to when death has occured or is it down to the subjective but informed judgement of the doctor?
