Gould comienza describiendo cómo el panda gigante posee un "sexto dedo" formado por el hueso sesamoideo radial, agrandado.

Stephen Jay Gould was a vocal advocate for the theory of evolution, and his work continues to influence contemporary discussions on the subject. In "The Panda's Thumb," Gould employs the panda's remarkable adaptation to illustrate several key aspects of evolutionary biology. He emphasizes the importance of understanding the historical and developmental context of anatomical structures, rather than simply focusing on their functional significance. Finch stood up

A paleontologist working in the dark, using the bones it has lying around—the ribs of a reptile, the jaw of a shrew, the wrist of a bear—to build a new tool for a new job.” Vance, you see a mess
