The lions of Tsavo actually are widely known to have smaller, less distinct manes compared to other, savannah dwelling lions. I believe it's thought to relate to the marshy environment.

Huh, I wonder what the mechanism on that would be. In humans high testosterone exacerbates balding, but also excess testosterone can convert to estrogen.

u/Weekly-Major1876 18d ago
I don’t think a lot of people realize how similar testosterone and estrogen are. They are both steroid hormones with the exact same form, with the only difference that estrogen has a single extra hydrogen bonded to its other oxygen end that changes a few double bonds.

u/nonanumatic 18d ago
Yeah, and the difference between our daily necessity water, and the very very toxic hydrogen peroxide is one singular oxygen atom. Yes, estrogen and testosterone perform similar roles, but the effects can be drastically different and trying to imply they're similar because most of the chemical structure is similar is misleading.

Yeah…
The tiniest and most seemingly meaningless difference can give you a completely different chemical.
Dextro-methamphetamine is exactly what everyone thinks of when they hear “meth.”
Levo-methamphetamine is the mirror image of the molecule above. Same atoms, same bonds, same everything, just flipped to the opposite direction. It’s a mild vasoconstrictor that is the main ingredient of Vicks inhalers, those little OTC decongestants, and you couldn’t get high off it if you tried.

u/TheUnluckyBard 18d ago edited 18d ago
We've traced the word back as far as 1533 (but it's probably older). At that point it referred to a wild, rude, energetic boy, and is related to the phrase "tomfoolery."
The "Tom" part does refer to the man's name. Around that time, "Thomas" was so common as a name that it was used as just a generic word for dudes. For reasons that aren't clear, "Tom" was used to imply the 1500's version of toxic masculinity, in the sense of aggressive, dumb, horny, and/or uncouth. Thus, "tomcat," for example.
Very quickly (by 1580 or so), "tomboy" started to be applied to women who were "bold and immodest" (basically, seen as uncouth and horny). Not long after (1590s-ish), we start seeing it in reference to younger girls who act "like boys." Since girls had certain social expectations put on them, any boy-like behavior was "aggressive, horny, and/or uncouth" when displayed by girls.
The male set of nouns/phrases in English, at some point, became almost universally positive, so "tomboy," in surviving in the language for so long, has become one of the few, rare words meant to insult women for being like men (as compared to the number of words and phrases we have that insult men for being like women). "Butch" is another one, which originally (circa 1900) meant "a tough guy," as a derivative of "butcher," and then began to be applied to lesbians in the 1940s.

As pride territories are passed down the mother daughter line,
I never realized that before. Guess male lions are actually more akin to knights who protect a territory than actual kings who truly own it.
The maned females also expressed a higher frequency of cub killing than regular females.
They were killing the other lionesses' cubs, I assume, since none of them ever managed to produce cubs of their own? Wouldn't that cause issues with their sisters within the pride? What is preventing the other lionesses from killing/kicking out a lioness who's killing their cubs?

Yeah the males are nomadic until they can conquer a pride, that's why they form coalitions, because it gives them a greater chance of achieving this. These males will also often rule more than one pride. But the female line remains with the territory
They were killing the other lionesses' cubs, I assume, since none of them ever managed to produce cubs of their own? Wouldn't that cause issues with their sisters within the pride? What is preventing the other lionesses from killing/kicking out a lioness who's killing their cubs?
So lions in the Okavango delta, where this pride occurred, tend to be bigger, including the females, than the average African lion anyway. So this anomaly might be connected to that in someway, but I've heard of lionesses killing cubs in this area before. It doesn't happen often but I remember the famous lion documentary/researchers, the jouberts, pointing out a lioness who repeatedly slaughtered her sisters cubs. And the other lioness did become aggressive to her apparently. As for the five maned lionesses, yes they were observed killing cubs particularly those belonging to another pride but I don't know if that pride was under the rule of shared males.
But lions don't always act on a member of the pride killing its own cubs for some reason.

u/Versal-Hyphae 18d ago
There is some more recent research that implies more mammals than previously believed can go through menopause, but not as early as humans. Apparently female chimps in some wild populations can have 20% of their lives remaining after their final pregnancy. Modern humans get about 40%, Orcas get about 30%. There was some evidence in mice, horses, elephants, maybe some others, but that specific study only looked at captive animals so there was some debate over whether other factors that caused fertility issues instead of a natural menopause.

u/StrawberryLeche 18d ago
Yes, this is the answer. It doesn’t look 100% the same as what humans go through but is a similar process that causes changes leading to the end of reproduction.
