# All fingers have the same shape

A 2022 study of handshapes found that 85.6% of handshapes in 33 sign languages conform to these biological tendencies. Additionally, 35 handshapes were found to be represented in 89.2% of the 33 languages examined. Handshapes that did not conform to these tendencies were common in fingerspelling. This may be due to fingerspelling being a result of culture and explicit learning rather than arising naturally.
