Answer:
The correct answer is option A. "Hormone receptors evolved later than many of the hormones with which they now interact".
Explanation:
It is false to affirm that hormone receptors evolved later than many of the hormones with which they now interact. There are multiple scientific studies that support the theory that receptors and ligands evolve at the same time in what is known as "synchronous birth". Receptor and ligand interactions are key components in the processes of living organisms, therefore, it they should evolve together in order to be functional.
They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves.
