[quote="ob"]Ok, letâ€™s get down to the nitty-gritty. The paragraph contains a belief and an alternative opinion.
The belief is that evolutionary pressure to increase the number of goats so as to ensure a diverse gene pool (EP) has caused the unusually high frequency of small goats in island populations (F).
EP -> F.
The alternative opinion is that the reproductive success of a trait (RS) is the only pressure that influences its frequency (F). In other words it contradicts the previous statement.
RS -> F.
The author puts forth that the reason there are so many small goats in island populations is that this trait is predominant.
A tells us that EP -> RS. Nope.
B says that NOT RS -> F. Nope.
C â€“ â€œsay again?â€
