Early and intermediate horses had three foot bones (two small and one large), and modern horses have four foot bones (three small and one large).

The earliest horses had four foot bones (three small and one large), intermediate forms had three foot bones (two small and one large), and modern horses have a single large foot bone.

Answer 1

The correct response is:

The earliest horses had four foot bones (three small and one large), intermediate forms had three foot bones (two small and one large), and modern horses have a single large foot bone.

This reflects the evolutionary trend in the adaptation of horses from multiple smaller foot bones to a more efficient single large foot bone structure, suited for their environment and mode of locomotion.
