What the simple mathematical abilities of animals can tell us about ourselves

Ars chats with UCL’s Brian Butterworth about his new book Can Fish Count?.

What the simple mathematical abilities of animals can tell us about ourselves

We often think of mathematical ability as being uniquely human, but in fact, scientists have found that many animal species—including lions, chimpanzees, birds, bees, ants, and fish—seem to possess at least a rudimentary counting ability or number sense. Crows can understand the concept of zero. And a study published in April found that both stingrays and cichlids can take this rudimentary "numerosity" to the next level, performing simple addition and subtraction for a small number of objects (in the range of 1 to 5).

The latter study's conclusion doesn't surprise cognitive psychologist Brian Butterworth, an emeritus professor at University College London and author of a new book, Can Fish Count? What Animals Reveal About our Uniquely Mathematical Minds.

"There are lots of animals that can do addition and subtraction," Butterworth told Ars. "Bees can. Bees can represent zero as well. So it's not surprising to me that stingrays and cichlids can do it." His book explores how the ability to process mathematical information and extract numerical data from their environment is critical to an animal's ability to survive and thrive. In fact, there might just be an innate understanding of math at its most basic level that was passed down the evolutionary chain from our most distant common ancestors.

Rocket Report: India wants its own SpaceX, Firefly targets July for Alpha launch

Welcome to Edition 4.45 of the Rocket Report! Just as a programming note, I'll be traveling during the second half of next week for a family reunion, so there may or (may not) be a report next week. Thank you for your patience.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Firefly targets July for second Alpha launch attempt. Nine months have passed since Firefly's Alpha rocket launched for the first time, lifting off from Vandenberg Space Force Base in California. Unfortunately, one of the rocket's four main engines failed about 15 seconds into the flight, and the rocket was lost about two minutes later. The period since then has been a difficult one for the company and its founder, Tom Markusic. In addition to dissecting the cause of the Alpha failure, Firefly also ran afoul of rules set by the Committee on Foreign Investment in the United States, CFIUS.
