Today we learn about the myth of bigger male mammals, explore what OpenAI’s Sora text-to-video AI tool might mean for science and consider the way we think about menopause.
A group of female northern elephant seals (<i>Mirounga angustirostris</i>) and a single larger male, who is easily identified by his prominent snout.
The most dimorphic species was the northern elephant seal (Mirounga angustirostris), where males had a mean mass 3.2 times that of females (Michele and Tom Grimm/Alamy)

Most male mammals aren’t larger


An analysis of more than 400 mammal species is overturning Charles Darwin’s assertion that in most, males are larger than females. In fact, this is only the case for 45% of species, with 39% showing no sexual size dimorphism and 16% having larger females than males. “There’s been this really strong inertia toward the larger male narrative, but it was just based on Darwin’s hand-wavy statement, and the evidence doesn’t really support it,” says evolutionary biologist and study co-author Kaia Tombak.

Sorry, Darwin: Most male mammals aren't bigger than females
'It’s very Victorian Era thinking about gender roles.'
Montana traffickers illegally cloned Frankensheep hybrids for sport hunting
Conspirators used the genetic material of Marco Polo argali sheep from Kyrgyzstan to breed entirely new animals.
Cicadas pee in jet streams like bigger animals
Other insects flick urine away in droplets, but that can waste energy for hungry cicadas.

Book Excerpt: In Animals, the Thin Line Between Play and Dreaming

By David Toomey
Psychologists and cognitive scientists are probing the mysteries of play and dreaming among animals, which may be intimately connected. Since dogs, horses, birds, and many other creatures dream, evolutionary biologists assume that it must have adaptive advantages. But what are they? Read on »
