You can get males that look like females. They have the XY chromosomes.biological sex itself, which is always binary, with just two sexes
I don't think Dr. Coyne got any of the details wrong but you're free to judge for yourself.Looks like the video is not worth watching.
In fact, it’s estimated that nearly 2% of live births are born with congenital conditions of atypical sex development. That basically means that something in their chromosomes, hormones, gonads, or genitals is different from what many people expect of a “boy” or a “girl.” This used to be known as being intersex, but these days, it’s better described as having differences of sexual development, or DSDs.
Nonsense.Or this one

Forget the details. What are the broad strokes of his argument, in your own words?I don't think Dr. Coyne got any of the details wrong but you're free to judge for yourself.
I like Novella, but he is a quack on this issue. He has either not read the Cass report or is deliberately misreporting it.Contrariwise...
I don't much like this approach, since it lends itself to strawmanning, whether by accident or on purpose.Forget the details.
Basically sex exists as an evolutionary adaptation and there are only two sexes which may make use of that process to pass on their genes. Intersex individuals exist, but they do not constitute a third sex.What are the broad strokes of his argument, in your own words?
So what you are saying is that your two sexes, male, female, and none of the above?I don't much like this approach, since it lends itself to strawmanning, whether by accident or on purpose.
Take my summary with an ample helping of salt, but please do listen for yourself sometime.
Basically sex exists as an evolutionary adaptation and there are only two sexes which may make use of that process to pass on their genes. Intersex individuals exist, but they do not constitute a third sex.
(Usual caveats apply, e.g. anisogamy.)
If you looked at the video you will know.So what you are saying is that your two sexes, male, female, and none of the above?
You have exactly two kinds of mammalian ancestors; none of them were none of the above.So what you are saying is that your two sexes, male, female, and none of the above?
Just watched it. He is not talking about who your ancestors were. He is talking about the population. He is also wrong about people never talk about what types of non-binary sex people are. My video is all about that.You have exactly two kinds of mammalian ancestors; none of them were none of the above.
As I said, there are two sexes which make use of sexual reproduction to pass on their genes.
For more details and clarifying background, I would encourage you to take the time to watch the video.
That is a gross misrepresentation of what he said. You claim to have watched the video, but its clear that if you did so, you were not paying attention. It was absolutely clear in his video that what he was talking about is self-identification of a gender other than your sex. This ONLY happens in humans.... there are no stallions who identify as mares, no male dogs that identify as bitches, no tom-cats who identify at she-catsIn the link below it also mentions that some cats have XXY chromosomes. So he is wrong to say this sort of thing only happens in humans.
that is a very silly argument, and it is wrong: depending on the upbringing, pets can very clearly identify as a different species than their own, adopting characteristics of the other pets in the household.That is a gross misrepresentation of what he said. You claim to have watched the video, but its clear that if you did so, you were not paying attention.

At no point did he ever say that species other than humans do not have DSD.
DSDs are not additional sexes.Or this one

Matter of definition. They are neither male, nor female.DSDs are not additional sexes.
This is complete BS. When a cat behaves like a dog in a home environment, that is learned behaviour, usually, and often inadvertently, encouraged by the owner. It is not a behaviour brought about by the cat having a predisposition to behave like a dog.that is a very silly argument, and it is wrong: depending on the upbringing, pets can very clearly identify as a different species than their own, adopting characteristics of the other pets in the household.
Human-centric chauvinism is very rarely anything other than lack of observation.
The population came from somewhere; Coyne says how at around 16 minutes into the lecture when making the claim that "there are no exceptions" to the gametic binary in animals.He is not talking about who your ancestors were. He is talking about the population.
I wonder what is left on topic now. Like, um, race science?Deleted, so as to not fall foul of Darat's post above.
