- Why is it interesting that Homo luzonensis was found on an island? A. The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island B. The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raft C. The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them D. The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were therearrow_forwardDespite the differences in neck length, mice, humans, and giraffes all have seven cervical vertebrae.

They are newly developed structures found in modern whales due to mutations. B. They are examples of fossilized remains of ancient organisms. C. They are traits acquired by modern whales over time as they adapted to living in water. D. They are vestigial structures which are remnants of structures that served a function in the organism’s ancestors.arrow_forward
