How can evolution create BOTH man and woman?

[aldon]

I would like some of your opinions on this topic. If we did evolve from an evolutionist standpoint, how were two different beings, man and woman formed. I understand the whole evolutionist concept in how humans were created, but what confuses me is how would evolution develop both, man and woman, the objective being reproduction of humans. I can see atoms in the beginning developing a living being of one kind, without the capabilities of reproducing, but to form male and female is a little baffling. I am not advocating evolution or creationism herem just would to hear some input. Thank You.

maybe a mutation of x gene to y gene???
...but some organisms are just the opposite, xx=male, xy=female...

mutations usually don't form useful, working parts. mutations are usually described as defects.

So, what you're saying is that either men or women are mutations. or were

[TeleMad]

As far as HUMAN male and female, they each evolved from PREHUMAN male and female. It's not like what humans evolved from were all males, and then one day was born two humans - one male and one female.

As far as the simplest example of sexual reproduction, I think it is found in bacteria that undergo conjugation (it;s been a while so I may be wrong, and I'm too laze to look it up right now. But anyone interested could at least start by looking at a bit of info on it).

This is a Creationist LIE.

EVERY new life is a MUTATION of the previous, unless it is a PERFECT CLONE.

However if you wish to classify YOUR mutations from your parents as DEFECTIVE...

Now as to reproduction.

On a basic level, (contrary to the LIE I responded to earlier) mutations increase the possibility of continuation of the species. The greater the variety, the greater the chance of a particular species being able to suvive a changing environment.

One method of genetic mutation is bi-sexual reporduction.

Remember, not all species reproduce bisexually.

Organisms that reproduce by the merger of two DIFFERENT source genes can have a wider range of mutations in a smaller number of generations. This provides a greater assurance of diversity to survive changing environmental conditions.

Note "usually." Some mutations in humans are anything but useful to "survival," such as being born with too many or too few fingers. Too many crowds the hand. Too few makes the person unable to grasp certain objects.

Three makes for a good cartoon.

yeah, most of the time, but harmful mutations are not selected by natural selection. only useful ones (or netural ones) are inherited to the offspring.

organisms w/ harmful mutations are less likely to survive, thus producing less or no offspring.
