Someone asked something simular to this but it was poorly worded, offended many people and was deleated by yahoo. Personaly, I don't believe in evolution. I'm not asking what you think. Just what Darwin thought.

I am easily confused with the number of chromosomes and chromatids at different stages of the mitosis and meiosis. Can someone tell me how many chromosomes are in each stage and how many chromatids are in each and how many are in the female's first polar body and second polar body, and how many are in spermacyte and spermatids and sperm. How many chrmosomes and chromatids are in the wording of tetrads, dyads and monads?

Aren't they interferring with the evolution of mankind by tampering with the mortality of the sick and dying? Isn't medicine keeping the weakest of mankind from dying and thus preventing the species from evolving further by means of those who can adapt.

A work colleague of mine believes that your brain would explode/impode if you were to hold your eyes (out of your head but still attached) looking into one another.

His reasoning is that the brain would not be able to process what is happening.

Any suggestions or comments I can pass his way?

Not looking for reactive responses, nor am I aiming to make people angry. I repect all points of view and this is just something I've been wondering about.

I'm asking this, because I was recently reading the definition of the scientific method in a science textbook, and part of this describes this method as "test with experiments". Since you can't test, or observe, cross-species evolution in an experiment, would that then make large-scale cross-species evolution only theory, and not science?

I understand that mutations and small-scale evolution can be observed (such as changes in fruit flies, moths, etc.) but the changes of one species into another can't be observed or recreated in experiments. Would this then render evolutionary as a theory unable to be verified by the scientific method?

Again, no reactive responses please. I'm just interested in learning.

Thanks.

The transmitter and the receiver both have to work very, very well for it to be useful to the bat. If a bat had one or the other parts of the mechanism that are only "part way done", it does the bat no good, and would provides no competitive advantage for survival, as I understand the theory of evolution.

For purposes of discussion, suppose it took 10,000 gradual mutations for the whole thing to work at all. After 1,000 mutations, it is still useless.

Yet, my understanding is that the earliest bat fossils are fully formed ... there aren't 'links'.
