A recent study evaluated handedness across 172 animal species, revealing that left-handedness is common among various species. Historically, left-handedness was considered a human trait, as traditional assessments focused on metrics like writing. However, when assessing natural behaviors, researchers found that many species exhibit pawedness or flipperedness, debunking this misconception. The study categorized species based on symmetry and individual-level asymmetries, highlighting that nearly 75% of species showed handedness preferences, demonstrating a significant behavioral trend across the animal kingdom.
A recent study analyzed handedness in 172 animal species, revealing that left-handedness is common across the animal kingdom, challenging traditional misconceptions about handedness being unique to humans.
Researchers found that while over 25% of species showed no evidence of handedness, nearly 75% did demonstrate left or right preferences, especially in natural behavior tasks, like reaching for food.
