Assignment:

Watch this video and answer the questions

1. What explanation does the narrator give for why we have hiccups? (What function did this serve in the basal ancestor possessing this trait)

2. What drove the fish to shallow waters and why was this ultimately a possibly deadly new habitat?

3. Name three adaptations the documentary developed by reptiles that were not possessed by fish. (may include adaptions held by the intermediate group of amphibians).

4. What does the video say happened in Siberia 250 million years ago? What gas was released and what did that gas do to change our planet?

5. What explanation does the narrator provide for goosebumps? What other adaptions mentioned in this part of the documentary allowed early mammals to survive alongside the dinosaurs?

6. What bone is mentioned as being a remnant from our ancestor's days in the trees? What was the alternative means of transport our ancestors chose once moving tree to tree was no longer an option due to ever sparser forests where out ancestors lived?

7. What was the new behavior seen in hominids 1.8 million years ago? What did they learn to make this new behavior more successful? (hint: I don't mean running, it is specifically stated as something "we learn")

8. Using what you saw in the documentary with regard to what made a species more successful in their given environment to answer the question "If humans evolved after monkeys, why do monkeys still exist". (hint: it is a similar line of logic to why bikes still exist even after cars were invented or why a pencil is still useful for certain things despite our newer invention of the ballpoint pen that serves a similar purpose)
