39. Around the turn of the 19th century, scientists (naturalists really) were gathering evidence to realize that there used to be species on the planet that were not around today. An archeologist would like to study evolution. He has far to look at some evidence. This is evidence known a) Skull and bones b) Cultural remains c) Tools and leftover food d) Fossils 40. Same archeologist ran into some troubles. During his discovery of the evidence he learned that it can all fit in the back of a truck. Since we do not have a living close relative, the closest thing we can compare ourselves to is/are a) Chimps b) Gorillas c) Chimps and gorillas d) Monkeys and chimps 41.
