Question

Consider the keyboard on a typewriter, a laptop, and a smartphone would you consider these to be homologous structures or analogous structures?

Answer 1

Analogous structures

Step-by-step explanation:

Homologous structures are the one that may look alike by appearance but may not serve the same purpose.

While analogous structures may look different from each other but have similar function.

The purpose of having a keyboard is same in case of a typewriter, a laptop, and a smartphone though they look different from each other. Thus, they can be considered as analogous structure.
