1. Let’s say you’re hanging out with family around the dinner table, and between mouthfuls of turkey they ask what you’ve learned about dinosaurs. You reply that one of the most interesting things you’ve learned is that all birds ARE dinosaurs, including the turkey that everyone is eating! Your family is skeptical, and concerned that you’re being taught a bunch of rubbish. What FIVE lines of evidence would you use to respond? In other words, of all the evidence we’ve discussed, what FIVE things do you think best demonstrate the evolutionary link between dinosaurs and birds? Remember, you’re trying to convince your family, so you also need to EXPLAIN THE SIGNIFICANCE of each piece of evidence.
2. Read this National Geographic article (https://www.nationalgeographic.com/magazine/2018/01/why-birds-matter/) and answer the following questions:
(A) About how many bird species are there? (It’s worth noting that there are about 5000 species of mammals.
(B) Thick-billed murres use their wings to fly and swim, diving into oceans to feed. How deep can they dive?
(C) Corvids (which include crows, ravens, and jays) are among the most intelligent and social of all birds. The article refers to a YouTube video of a crow using a lid for what purpose?
(D) There’s an individual bird, a red knot tagged as B95, that has flown more miles than separate what two objects?
(E) At one point, the author quotes Shakespeare to epitomize the whole point of this essay. Read the last four paragraphs closely, and explain how King Lear’s lament (“”O, reason not the need!””) relates to why we should value birds.
Earth Science – Dinosaurs
The present scientific consensus is that birds are a group of maniraptoran theropod dinosaurs that originated during the Mesozoic Era. A close relationship between birds and dinosaurs was first proposed in the 19th century after the discovery of the primitive bird Archaeopteryx in Germany. Birds and extinct non-avian dinosaurs share many unique skeletal traits (Chiappe, Luis M. 2009). Tyrannosaurus rex was a theropod, so was Velociraptor. A suite of skeletal similarities offers the best evidence of the connection between theropods and birds. Of all the Hollywood dinosaurs that we know and love, Velociraptor is the closest relative of modern birds.
