A scientist examines the embryos of a penguin, a duck, and a bat. She finds that the embryos of penguins and ducks develop in a similar way, whereas the embryos of a bat develop in a way that is different from penguins and ducks. Which statement BEST explains this observation? A) Penguin and duck embryos develop in a similar way since they both have similar ecological roles. B) Penguin and duck embryos develop in a more similar way due to the greater number of chromosomes present in these species. C) Bats experience more genetic mutations that do penguins and ducks and are likely to develop differently as a result of these random genetic changes. D) Penguins and ducks develop in a more similar way since their common ancestor is more recent than the common ancestor of penguins and bats or ducks and bats.

The correct answer is (D) Penguins and ducks develop in a more similar way since their common ancestor is more recent than the common ancestor of penguins and bats or ducks and bats.

The birds such as penguins and ducks develops in a similar way since their common ancestors are more recent as compared to the common ancestors in case of penguins and bats or in case of ducks and bats. The birds and bats do not share any recent common ancestors according to the phylogenetic tree.
