Scientists theorize that the ancient horse on the left is related to the modern horse on the right. The scientists theorize that the horse has gone through many changes over time. How did the scientists conclude that the animal changed over time?
by examining fossil records
by learning about natural selection
by studying deposition of sediments
by observing different types of rock formations
A scientist drew some diagrams of ancestors of elephants based on fossil evidence. Which is the BEST conclusion that can be made from comparing the diagrams?
(Model Description: The first elephant ancestor is 50 million years old and very small, the second elephant ancestor is 30 million years old and much larger. The trunk is also short. The last ancestor is 20 million years old and taller, but shorter width wise. The trunk is also longer.)
Ancient elephants were better adapted than modern elephants.
Elephant habitats have remained the same over time.
Elephant fossil evidence is widespread and complete.
Elephant species have changed over time.
Fossils are the preserved ____ of once living organisms.
plants
adaptations
remains
variations
Why are there more animal fossils than plant fossils?
Animals are smaller than plants, so they break down faster.
Animals eat plants.
Plants have harder bodies than animals, so they break down.
Plants have softer bodies than animals, so they break down.
An animal fossil has sharp, pointy teeth. What can we infer about this animal?
The animal lived in the water
The animal is a carnivore (only ate meat).
The animal lived near the beach.
The animal is an herbivore (only ate plants).
If a scientist found a fish fossil in the desert, what can they infer?
An animal ate the fish.
Today's fish looks the same
That water covered the area long ago.
The fish is endangered.
