Six potential species of seaside sparrows were genetically analyzed to determine their phylogenetic relationships. DNA analysis revealed that there were only two monophyletic groups with individuals from three subspecies making up each group. The three Atlantic coast subspecies formed one monophyletic group, while the three Gulf coast subspecies made up the other monophyletic group. If you could only save two subspecies of the seaside sparrows from extinction, would you choose two subspecies from the Atlantic coast, two from the Gulf coast, or one each from the Atlantic and Gulf coasts?
A) Save two subspecies from the Atlantic coast, as this coastline is longer and more likely to provide habitat for the birds.
B) Save one each from the Atlantic and Gulf coasts to preserve more genetic diversity.
C) Save two subspecies from the Gulf coast, as this area is much warmer and birds are more likely to survive.

Saving one subspecies from each coast would preserve more genetic diversity and ensure that both monophyletic groups are represented. This approach would also prevent the loss of any unique adaptations or traits that may be specific to one of the coastlines.
