Which of the following animal pairings demonstrates the principle of convergent evolution?
Correct Answer: B.The shark and the dolphin
Convergent evolution is the process where organisms from different ancestral linage, grow to look alike and share similar physical characteristics because they live in the same or very similar environments. Whereas divergent evolution is defined as the evolutionary process whereby organisms from the same ancestral lineage differ in appearance. This difference would result because of the different habitats of the organisms. Only the shark and the fish are from different animal lineages and look very similar because they both live in aquatic environments. The other animal pairings all originate from a similar ancestral lineage and have grown to look very different over time because of their terrestrial habitats.
The Medical College Admissions Test (MCAT) is a test administered by the Association of American Medical Colleges (AAMC). The test is designed to test your knowledge in three specific sections; physical sciences such as physics and general chemistry, biological sciences and organic chemistry, and verbal reasoning.
How Should I Study?
The MCAT is a rigorous exam that requires months of planning in order to achieve a great score. It is recommended that you begin your study schedule 3 months prior to your exam date. In addition to answering our practice MCAT questions each day, read this article regarding studying for the MCAT from home.
Register for the MCAT.
The first question many people ask is, “when should I take the MCAT?” The general guideline is to take the MCAT the year before you plan to enter medical school. For example, the class of 2018 should take the MCAT sometime before or during the spring/summer of 2013. Your basic science coursework should be complete by this point.
