Evidence for Evolution

The fossil record provides evidence of how things have changed over time. The table below shows the evolution of the origin of Tetrapods.

When looking at the fossil record above, what conclusion can be made based on the evidence?

• None of the organisms are related.

• Tulerpeton is related to living tetrapods, but not to Tiktaalik

• All of the organisms have a common fish ancestor.

• Ichthyostega are more closely related to living tetrapods than to Tulerpeton.

The occurrence of the same amino acid sequence in digestive proteins in two morphologically unrelated species provides evidence that these two species —

• occupy the same niche

• have annalogous structures

• descended from a common ancestor

• have evoloved convergently

The wing of a bat, arm of a man, and flipper of a whale have similar internal structures. Even though these structures have diverse functions, their similarities suggest-

• Development in similar environments

• Similar reactions to environmental stress

• Separate development merging to a common form

• Development from a common ancestor

Horses belong to an order of organisms called Perissodactyla, or odd-toed ungulates. The distinguishing characteristic of odd-toed ungulates is that their third, or middle toe, is the largest, while the other four toes are reduced or absent.

Based on this information, which organism shares the most recent common ancestor with the modern horse and would also be classified as Perissodactyla?

• Cow

• Tapir

• Dog

• Pig

Cetaceans are whales and their relatives. The diagram shows some fossils of cetaceans.

Which statement provides the best evidence that Ambulocetus natans is an ancestor of Basilosaurus isis?

• Homologous structures occur in each fossil.

• Similar nitrogenous bases are found in the DNA of each fossil.

• The fossils were found in different locations.

• The youngest fossil is larger than the older fossils.
