Intelligence: Dogs vs Cats

A new study seems to have provided an answer to the age-old question of who is smarter: dogs or cats? The speculation before the study was conducted was that hunting may require extra brain cells (neurons). If true, that would mean that cats would have more neurons than dogs. My apologies to all of the cat lovers out there. The findings from the study suggest that dogs may actually be […]

Sheep can recognize human faces

New research published in Royal Society: Open Science shows that it is possible to train sheep to distinguish between different human faces shown in photos.  In fact, 8 out of 10 times, the sheep were able to choose the image they had been trained to recognize. According to study author Dr. Jenny Morton, “…sheep have advanced face-recognition abilities, comparable with those of humans and monkeys.” Because these animals are rather […]

#1: Is there an evolutionary advantage to “being stupid”?

And the #1 blog entry published thus far in 2017 discussed whether there was an evolutionary advantage to being stupid: —- As I was looking through the scientific literature the other day, I came across an article published in 1973, “The Evolutionary Advantages of Being Stupid.” With a title like that, how could I not read it? In this article Dr. Eugene D. Robin discussed how larger and more complex brains are […]

Pigeons outperform humans when it comes to multitasking

Sara Letzner had humans compete against pigeons in a behavioural experiment. Photo from: Ruhr-Universitat at Bochum A new study conducted by Drs. Sara Letzner and Onur Gunturkun (Ruhr-Universitat at Bochum) as well as Dr. Christian Beste (Technische Univeritat at Dresden) shows that pigeons are better than humans when it comes to multitasking. Their findings were published in Current Biology. The findings from the study show that the mammalian cerebral cortex, with […]

Is there an evolutionary advantage to being ‘stupid’?

As I was looking through the scientific literature the other day, I came across an article published in 1973, “The Evolutionary Advantages of Being Stupid.” With a title like that, how could I not read it? In this article Dr. Eugene D. Robin discussed how larger and more complex brains are associated with greater intelligence, which by evolutionary standards was thought to be related to “superiority.” He described how this line of thinking […]

Pigeons can identify words

A study recently published in the Proceedings of the National Academy of Sciences provides evidence that pigeons can learn to recognize words. That is after the birds were trained over a period of 8 months. According to the study authors “The pigeons’ performance is actually more comparable to that of literate humans than baboons’ performance.” To read, we must be about to decode letters and the sounds they make as […]
