Earth –A Home for Life 300 During the Permian Extinction, about _______ of the species living in the ocean became extinct. 90% C. 50% 10% D. 1% What is A. 90%?

Earth –A Home for Life 400 Scientists think that this is what caused the Permian extinction 250 million years ago and how and why it may have happened. What is what is the Earth’s land masses joining together causing 90% of the species in the ocean and many land dwelling animals to die ? The formation of one big continent changed the climate and conditions in the ocean.

Earth –A Home for Life 500 This is when, why and how scientists think the Cretaceous extinction happened and what disappeared. What is 65 million years ago scientists think that an asteroid hit the Earth which caused a climate change and the dinosaurs disappeared? After the dinosaurs died out, many new mammals began appearing.

Species Change over Time 100 The relative age of a fossil tells you a. whether one fossil is older or younger than another fossil b. exactly when a fossil was formed c. the amount of radioactivity in a fossil d. how long the fossilized organism was alive on Earth What is A, whether one fossil is older or younger than another fossil?

Species Change over Time 200 Lamarck proposed that species evolve because: they adapt to their surroundings over time. they can pass on traits acquired during their lifetimes to their offspring. they overproduce and a variety of species come from each offspring. natural laws decide when they should change. What is B, they can pass on traits acquired during their lifetimes to their offspring?

Species Change over Time 300 Most__________ will become more common from one generation to the next. variations mutations speciations adaptations What is c speciations?

Species Change over Time 400 According to Lamarck, could the parents of the tortoise from Abingdon Island be born with a short neck? What is yes, they could have stretched their necks during their lives and then passed on that trait to their offspring?

Species Change over Time 500 This is how variation and adaptation may have led to the development of long-necked tortoises on Abingdon Island.

Species Change over Time 500 Answer Slide The offspring of the ancestors of present-day tortoises on Abingdon island differed from each other in small ways. One of these variations was likely neck length. The tortoises competed with one another for leaves. The better adapted tortoises, with long necks, survived and reproduced at a higher rate. Therefore, long-necked tortoises became more widespread.
