• To find patterns of genes inherited together in families with phobias.

• To study the impact of therapy on phobias.

• To identify environmental causes of phobias.

What role do evolutionary pressures play in the development of phobias?

• They make phobias less common.

• They have no impact on phobias.

• They influence the heritability of different phobias.

• They cause all phobias to be learned.

• Cognitive behavioral therapy.

• Medication only.
