And I never said a study is wrong for being a study

it is a FACT that male genetic material is what determines the sex of a baby...

in contrast to what they used to think...

So again... the ONLY way you can know if you believe the assertion or not is to review the study...

Well, if they USED to think that (meaning a former fact), how do we know a current fact won't change to an updated fact ?

We have to determine what the definition of fact is. Is a fact eternal, or can a fact be changed into a new fact based on new understanding ?

Because back then they didn't know about cells, alleles and genetics... now we do

just because knowledge changes does not mean something can not become fact

And aren't there further things of which we don't yet know ?

You're always sounding like we've reached the absolute pinnacle of what we can know

when you learn about things you can't see, such as alleles, then you are able to answer questions

I never said we have reached the pinnacle of what we know. LOL

But we HAVE, through learning about cells and genetics, benn able to answer some long asked questions

Because you sound as if all the things the scientific community says is 100% factual, those things could never change based upon greater technology or more information.

you sound like you are unwilling to believe anything no matter what eveidence is presented

I never said things can't change... but not ALL things

I'll have to rejoin this lovely conversation after work. I get off in an hour, sorry guys!

there are some things, that we now know are FACTS..

I never said that. I haven't said what I personally believe about individual things, I'm making general statements about thought and scientific processes, independently of what I personally believe about a specific subject.

it is a FACT that the genetic material that chooses the sex of a child is from the father. We have identified the chomosomes involved. The chomosomes are the smallest thing there is on that score.

that science is settled...

Also, when I type 1 single messages, you've typed 5 or 6, so then the thoughts get so intermingled it's more difficult to expound on what both of us are saying

OK... then I would ask you to watch the show I liked above

Which I can do.

then we should talk about intelligence in animals

Now that that is out of the way.....................

But you also have to send me whatever studies you got your information from

Even chromosomes could be examined in a greater way with future technology, you just can't know.

otherwise I am at a disadvantage

The science of how chomosomes determing out genetic makeup is a settled science. We can study dofferent ones, and how they make us who we are. But that's all

We can study how damage to them can damage us... but that is all

Wasn't it settled at some point that the Earth was flat, or the center of the universe ?

there is nothing other than chomosomes that determine the geneticmakeup of a lifeform

That is a different science and not relevant here

We used to say it was settled science that the atom was the smallest particle.

and there are still morons that think the earth is flat.

Funnily enough, the flat-Earth movement is actually growing, lol.

Yes... we know that there are smaller particles... but at some point you DO get to pretty much the smallest one
