– When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution.  – Sharks and whales both have streamlined bodies and tail flukes. True or False: We know that these similarities are because of convergent evolution because sharks and whales are not closely related and did not inherit these traits from a common ancestor. Whales evolved from tetrapods; sharks did not. 

Introductory video: Fossils provide us with a historical record of life on Earth. There are many types of fossils, from extraordinary unaltered remains trapped in permafrost or amber, to subtle traces of past activities in the form of footprints and burrows. The fossils that we have found provide windows into the past and direct evidence of evolution. Before you start the first level in this mission, “Eating dinosaurs for dinner,” watch the introductory video and answer the 2 questions below.  True or False: The oldest fossils can be found in higher layers of rock. 

Red, green, and gecko: Your first question is simple: Is a fungus more closely related to an animal or a plant? At first glance, many people might be tempted to say plant—but be careful! First impressions can be misleading.  In this level, be sure to read and follow the prompts. The prompts are there to help you get the hang of things. When you’re done, answer questions below before you move on to the next level, “Familiar faces.”  Under a microscope, the cells of mushrooms, plants, and animals all have visible nuclei. This makes them all:
