Humans carry a variety of non-functional genetic sequences, called processed pseudogenes, in their DNA. We can estimate how long ago these sequences first appeared in the genomes of our ancestors. In humans, processed pseudogenes include the three options below. Which of these would be least widespread among other primate species?
A) alpha-enolase psi1 (11 million years old)
B) AS psi7 (16 million years old)
C) CALM II psi3 (36 million years old)
