Động vật cũng có chi thuậnCác nhà tâm lý học thuộc ĐH Belfsat, Bắc Ireland vừa phát hiện, chó, mèo, vẹt, thậm chi cả cá cũng thuận “tay” trái hoặc phải.
ghiên cứu tiến hành trên nhiều loài vật khác nhau và cho ra kết quả bất ngờ. Với nhóm 42 chú mèo, họ phát hiện những con cái thường thuận chân phải, trong khi con đực thì ngược lại. Theo các nhà nghiên cứu, sự khác biệt này có thể do nền tảng hành vi khác nhau của chúng. Ví dụ, trong cách săn mồi, cách chăm sóc của cha mẹ, thậm chí cả chỗ ở tác động đến việc chúng thuận chân nào.Loài chó cũng vậy, trừ những con bị hoạn hoặc thiến.
