Question

zoogeographic regions are characterized by the presence of specific groups of animals. these regions are determined by the taxonomic or phylogenetic relationships of animals. the map shows the zoogeographic regions proposed by the naturalist alfred russel wallace in 1876. zoogeographic regions the similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between the organisms in both locations? a 1 and 2 b 3 and 4 c 5 and 6 d 7 and 8

Explanation:

For organisms to have common ancestry, they should not be separated by strong geographical barriers. Areas 7 and 8 are not divided by a significant geographical barrier (like mountains or large bodies of water shown in the map key). In contrast, other pairs (1 - 2, 3 - 4, 5 - 6) are separated by geographical barriers which would impede gene flow and make common ancestry less likely based on zoogeographic region logic (barriers limit species distribution and relatedness).

Answer:

D. 7 and 8
