Male birds are more likely to do so: After a five-year experiment, researchers from Florida State University and the Tallahassee-based Tall Timbers Research Station found that when fewer mates were available for brown-headed nuthatches, these small pine-forest birds opted to stay home and help their parents or other adults raise their offspring… Associate Professor of […]
Popscience: No natural mechanism is remotely suggested, so we must assume that it is sheer mental power, of the sort that we species-ists once thought existed only in humans, that enables the hen bird to plan for her chicks’ future. Shame on us!
Yes, if you believe the mirror test proves it: The bluestreak cleaner wrasse has passed the famous mirror test for self-recognition (originally intended for primate apes and monkeys). According to a recent paper (open access), three out of four fish tested by researchers from Osaka City University in Japan were able to learn to identify […]
Dr. Egnor explains, “Language is a tool for abstract thinking—a necessary tool for abstraction—and humans are the only animals who think abstractly”: In his discussion of why only humans have language, science writer Tom Siegfried gets a lot right, but he misses the crucial reason. … Siegfried is right that many non-human animals have the […]
The behavior of the slime mold (if that’s what it is) sounds altogether too modern for Dr. Cohen’s liking. That’s understandable. See, for example, “Is an amoeba smarter than your computer? (yes, in certain respects, it is) The trouble is, many forms of behaviour, like nest-sharing and parental care, have been found earlier than expected. We shall see.
Pat Suwonpanich has made a comment on hearing and sound as a mental phenomenon leading to questions of conscious mind that I think is worth pondering by one and all, so let us headline (with slight edits): >>For those who wanna read less-technical article on hearing, I have tried to write my own article as […]
It’s now thought that honey bees “shimmer” in order to protect themselves from hornets: What this essentially does it make is extremely difficult for hornets to swoop in and land on their massive huddle to prey on individual bees. Kastberger and his colleagues noted in their research that shimmering can create what they described as […]
Nature is full of intelligence but mostly it does not resemble human intelligence. In some ways it works better than computer intelligence.
The find kind of disappointed researchers who really wanted to know how humans come to use language but it is interesting in itself.
It’s not going to be easy.
That’s the surprising conclusion of a recent study that required rats who had had their ovaries or their uterus removed or both and then had to negotiate a water maze six weeks later: As compared with the other rats, animals who had only their uterus removed struggled more as the test became increasingly difficult. The […]
When pea aphids (Acyrthosiphon pisum) are fleeing a browsing cow, the tiny ones try to ride the much larger ones to safety: In a lab setup, hitchhiking got very young aphids safely across open ground about four times faster than scrabbling to safety on their own, the researchers found. These newborn aphids, not even 12 […]
According to the media release from Seals Unlimited, that is. No, but seriously: Dog lovers may be surprised (and displeased!) by a recent study of animal intelligence that dismisses the intelligence of dogs, compared to that of marine mammals: … systematically reviewing the animal cognition literature, British psychologists Stephen Lea and Britta Osthaus found dogs to […]
If you catch them at the right time. But can we give machines what the lizard has by nature? We sometimes assume that reptiles cannot be as smart as mammals because they are exothermic (cold-blooded) rather than endothermic (warm-blooded), and the brain is a high metabolic area. Here, though, we find some surprises. Reptiles lack […]
But they have quite different brains. The intelligence doesn’t seem to reside in the details of the mechanism Studying animals’ intelligence has taught us many things. But in some ways, it has deepened the mystery of intelligence. We might have thought that intelligence, in terms of individual learning ability, would gradually increase among animals, from […]
