The idea that power and oppression is a matter of 'evolutionary benefit' is highly dubious. There was no evolutionary benefit in oppressing black people.
That is why it was only started long after written history started, and ended very soon, compared to the oppression of women by men.
It was beneficial to a certain class of people for a limited time, but racism is nowhere as ingrained into society as misogyny.
It's just not as easy as 'the females are chased down and raped' nowhere near.
It depends on the animal species and on the individuum, but animals do rape. Dolphins are especially bad offenders. And you cannot claim that the females "enjoy all the sex"; they are left half dead after the rapes.
Yes, Victorian male scientists quite probably misrepresented the mating habits of a lot of animals to make it look like females were not free anywhere, as free female animals would have challenged the patriarchal society.
But this: "How maybe the dominant male doesn't force them into a group but they choose to congregate because of looking forward to the shagging, albeit with some 'flirty' stuff where the bloke tells them where to go." is nonsense, sorry.
The idea that males exerting dominance over women is "flirty" or "romantic" is very human. It developed in patriarchy. It does not make logical sense.
What's more likely is that the female animals all want to mate - because they have an urge to, and cannot rationally think about whether they want to be pregnant - but that they want to choose with which male animal to mate.
Which is what the dominant male tries to prevent. With more or less success. The argument that respecting the females would get him more sex falls part once you consider that the same is true for human males. Male animals who display sexual jealousy have more offspring in species where the female cannot put a firm stop to this, and then this becomes the normal/main way this animal mates.
And as for lions ... you may claim the female lion wants to be fucked, but you sure can't claim she wants the male lion to kill her young. Which is what male lions do. Killing lion babies they suspect were fathered by other male lions.
Of course it's totally different in the wild because a females fertile state is usually known. So comparing humans to other mammals hits a dead end a lot of the time because our sex and reproduction systems are so different.
That's why human males evolved a year-round patriarchy. Or perhaps the other way round, women evolved hidden fertility to counter patriarchy and be able to get good genes for their offspring despite patriarchy.
Male chimpanzees sometimes abduct young females to wait until they are fertile and then immediately rape them. That's a kind of proto-patriarchy right there.
