about 66 million years separate them, and the oldest human ancestors are only a few million years old, and Stegosaurus died out longer before T. rex lived than T. rex lived before you. - [13](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/13/) — Giraffes with slightly longer necks reached more food and won more fights, so they had more young, and over many generations necks grew longer; this is natural selection, and stretching your neck does not change what you pass on. - [14](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/14/) — A fossil is the remains or traces of a living thing kept in rock, such as bones, shells, footprints or even dung, and most fossils formed under water. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/15/) — The dodo of Mauritius could not fly and had no fear of people; it was wiped out in the 1600s by people and by the rats, pigs and other animals they brought, which ate its eggs. - [16](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/16/) — Wolves were brought back to Yellowstone in 1995 and changed where and how elk grazed, and some trees grew back along rivers; scientists still argue about how big this ripple was, but a top predator can shape a whole food web. - [17](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/17/) — The bald eagle came back after the pesticide DDT, which made its eggshells thin, was banned in the United States in 1972 and the birds were protected; a book called Silent Spring by Rachel Carson had warned about DDT. - [18](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/18/) — A tomato grows from a flower and holds seeds, so botanists call it a fruit, while cooks call it a vegetable; a potato is a swollen stem, a carrot is a root and broccoli is a bunch of flower buds. - [19](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/19/) — Dogs come from wolves tamed more than 15000 years ago and were the first tame animals, while cats came later to farming villages to hunt mice and were honoured as sacred in ancient Egypt. - [20](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/20/) — Elephants fearing mice is a myth; they are startled by sudden movement and wary of bees, and other myths are wrong too: ostriches do not bury their heads, lemmings do not jump and goldfish remember for months. - [21](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/21/) — Bees and other pollinators carry pollen between flowers so fruit and seeds can form, and about a third of our food depends on pollinators; wild bees need flowers and fewer poisons. - [22](https://md.mova.elamur.ai/free/en/corpora/school/biology/300-the-big-biology-quiz-part-3-dinosaurs-evolution-conservation-and-food/22/) — A child can help nature by leaving a wild corner, picking up litter safely, feeding birds, recording sightings for scientists and wasting less, and small acts by many people add up. - ← previous: [The big biology quiz, part 2: plants, the body and microbes](https://md.mova.elamur.ai/free/en/corpora/school/biology/299-the-big-biology-quiz-part-2-plants-the-body-and-microbes/) - next →: [Owls of the world: barn owls, eagle owls, elf owls and burrowing owls](https://md.mova.elamur.ai/free/en/corpora/school/biology/301-owls-of-the-world-barn-owls-eagle-owls-elf-owls-and-burrowing-owls/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
