DNA = Chromosome

Genetics as it applies to evolution, molecular biology, and medical aspects.

Guys you are mysogenists and sexist instead of scientific. Please tell me why the first homo sapiens cannot have been a woman. You both loose all your stars if you cannot do this. A simple reference to a published article in a refereed journal will do. I have the latest textbook "Introduction to Genetic Analysis" by Griffiths, et. al. 2008.

I say, that the first human wasn't woman, but I'm not saying, that the first human was man. First read something about evolution and speciation and than blame something

Cis or trans? That's what matters.

Jack you are now patronizing like your Indian guru. How can you say that the first human was not a woman. Is this because you believe in the Bible or the Koran? You have lost all your stars. Get laid, get a life and start doing some science instead of repeating others. The only time you were right was 2 months ago when you told me there were 46 chromosomes and 2 were sex. That leaves 44 to make 22pairs. 22+2 is 24!

The x and y chromosomes are also a pair, so it's still 23 PAIRSSSSSSSSSSSSSSS

Be polite here! Why are you mentioning Bible and Koran? I'm not insulting you, so don't insult me.

I said: "the first human wasn't woman, but I'm not saying, that the first human was man." and that's true.

You should prove your saings if you wish to prove biology wrong.

david23, did you see, read or hear this? unless you have seen it with your own eyes, do not believe it. Textbooks are often wrong and of no use either. Use your intelligence. Are there not 2 sexes? If X and Y form a pair would they not be an autosome? It is postulated that they evolved from an autosome. So far in 2 months I have not received one valid reason for pairing x and y and have given more than a dozen observable facts to show that each is a chromosome in his or her own right. Jack Bean is sure that the first human cannot have been a woman. But he does not know if it was a man. Perhaps a Chimpanzee? Ok if you support him but then also give a good reason. So far this website has been a joke and if there is a working biologist in the bioteam he should be sacked. Jack if you do not know an answer then it is perfectly ok to say so.

Jack Bean. I am not trying to prove biology wrong. And you were most impolite to me. From the start I have been asking what is the basis for pairing x and y. Look back on this forum and you will see that I have given many reasons why that cannot be so.
You do need to look honestly at your attitude towards the opposite sex!

sharan, you'll need to look beyond humans to see what's happened. Do a Google search for "evolution of the y chromosome", follow some of the leads, and get back to us if you still have questions.

Not really, you just mentioned, that at Human genome page they have them separate, what's logical, as they are not homologous and you only showed some page with bullshits on it. But you didn't show any reasonable reason for them not to pair.

Anyway, if they do not pair, how can they be securelly divided into new cells?
Also, the thing with animals. What about poor animal with three chromosomes (sorry, five, as X and Y are not homologous)¨, their chromosomes must me over-loaded as they must take care of so many organs...

what the heck is going on here. So what if the first woman is female due y came from x, why all the !!!!! and the religion stuff. I dont see why are you so passionate about something that holds no relevance to anything else. And who cares about how big the x chromosome is to the y, what are you even implying here. Both men and women only use only one x chromosome at any particular time anyways.

Are the chromosomes in each cell not how the body communicates with the Brain? If not, then what makes us humans tick. What produces consciousness ? Are you aware that our two eyes are very different? Male on the right and female on the left? Am I in the wrong forum?

Oh my. My personal thought was that the first human, was not male or female, but a combination of both. And so I went looking and sure enough, I found one that fit my way of thinking:
http://www.uchospitals.edu/news/1999/19 ... -vs-y.html
That the X and Y were really autosomes, and that thru the 4 events the articles lists, they evolutionized into what we see today.

What makes us humans tick, is the environment around us and the info that we process. Info processed makes consciousness. And everyone processes info differently, and even the info is different for everybody.
