A contested study suggests the ability to embed sequences within other sequences, a skill called recursion and crucial to grammar, has ancient roots.

Monkeys First, Then Crows In a 2020 study, researchers found that monkeys could generate recursive sequences after training. In the experiment, monkeys and humans were shown symbols, such as ...

A multi-institutional research team found the cognitive ability to represent recursive sequences occurs in humans and non-human primates across age, education, culture and species.

Here we present a new scheme for understanding the structural features and potential mathematical rules of symmetrical DNA sequences using a method containing stepwise classification and recursive ...
