At Mind Matters News: Why cats can remember other cats’ names

Cats are more intelligent than they have been given credit for in the past but they don’t do abstractions. To the extent that a cat recognizes his own name or another cat’s name, he interprets it as a signal that attention is being paid and that something may happen. Read More ›

At Mind Matters News: Can largely rearranged genomes explain why octopuses are smart?

Takehome: It’s still not clear just how intelligence develops in a life form. The relationship between massive genome rearrangement and very high intelligence in an invertebrate remains unclear but it is a promising research avenue. Read More ›

At Mind Matters News: Claim: Honeybees, “like humans” can tell odd vs. even numbers

Bees are not six-legged humans. They are incorporating the mathematical structure of the universe into their survival strategies. The researchers mainly demonstrated that we can use operant conditioning on bees. Read More ›

Male spiders have found a way to avoid getting eaten by their mates?

At The Scientist: After witnessing the odd behavior in the wild, Zhang and colleagues brought the spiders into the lab for a closer look. Using high-resolution cameras, researchers recorded males—which are less than a centimeter long—catapulting away from the female at speeds up to 88 centimeters per second (a little over 3 kilometers per hour).

At Mind Matters News: Evolutionary psychologist argues that worms feel pain. But how?

Wait. Barash’s hypothesis overlooks the fact that suffering is more than an alarm system. An alarm could be going off in an empty building. If some invertebrates show much more self-awareness than expected, it hardly follows that all do. We risk impeding humane reforms if we cast the net too widely. Read More ›

The oldest cephalopods — much older than thought — had 10 working arms, not 8

Wouldn’t that mean that the cephalopods had an even more complex nervous system in the past? For that matter, why do we hear about so much stasis and so little about evolution? The evolution must be happening very fast, punctuated by long periods of stasis. Read More ›

What bats learn from echolocation: “much more complex than previously thought”

This raises an issue: Social intelligence seems to imply an underlying intelligence in the universe. It’s not at all clear that it is merely a matter of natural selection acting on random mutations (Darwinism). For one thing, if there were no intelligence, there would be no need for social intelligence. Social intelligence is a response to existing intelligence. And no one knows how it arose. Read More ›

At Mind Matters News: The remarkable things we’re learning about bird intelligence

Crows and chimpanzees are thought to have last had a common ancestor 300 million years ago. Bees are thought to have had a common ancestor with them 600 million years ago. But crows, chimpanzees, and bees are all much more closely related to life forms that have not attracted attention for their intelligence. Are we just missing their intelligence? Or perhaps the question of unusual intelligence in some birds and other life forms but not others is one of the fruitful mysteries of science that invites further study. Read More ›

At Mind Matters News: The mystery of how newborns know things gets deeper

An innate program guides newborns to seek human faces and body movements but it wanes in favor of personal learning. But that may take longer for autists. Read More ›

At Mind Matters News: Source of most animal intelligence still a mystery

Question: Magnetic poles can shift. We can suddenly have north become south and south become north. The continents can drift. So can these animal behaviors accommodate changes in earth’s magnetic field or its geography in order to allow animals to continue to migrate? No one really knows the answers to this stuff as yet.
