Question 5444tple Choice Worth 3 points) (05.01 MC) West Indian manatees are large aquatic mammals that live in rivers and near shore estuaries, especially in Florida. They have two flexible front flippers with three or four toenails simitar to elephant toenals Though they tack hind limbs, manatees have vestigial petric bones as shown in the diagram Which of the following answer choices best describes how evidence of the manatee toenaits and pelice bones supports the scientific theory of evolution of these animals? The fact that manatees and elephants have toenails and pelvic bones suggests that their limbs evolved for similar use in similar environments The fact that manatees lack hind legs, unlike elephants, suggests that manatees and elephants evolved toenaits in parallel without any common ancestry The existence of pelvic bones and toenails in manatees and elephants suggests that manatees and elephants evolved from the same land animal The existence of pelvic bones and toenails in manatees and elephants suggests that these animals are evolving into similar animals

Answer 1

The existence of pelvic bones and toenails in manatees and elephants suggests that manatees and elephants evolved from the same land animal.This answer choice best supports the scientific theory of evolution by indicating a common ancestry. The presence of similar structures, such as toenails and pelvic bones, in both manatees and elephants suggests that these species share a common evolutionary ancestor, which is consistent with the concept of homologous structures in evolutionary biology.
