What is the title of the article?

• Physicists Create Five New Isotopes of Thulium, Ytterbium and Lutetium

• Dinocephalosaurus was Fully Marine Reptile and Even Gave Birth at Sea, Paleontologists Say

• 4.4-Million-Year-Old Ardipithecus Hand Reveals ‘Big Evolutionary Jump’

• New Species of Anaconda Discovered in Orinoco Basin

Where did Ardipithecus ramidus live?

• South America

• Europe

• Asia

• Africa

What is the name of the researcher from the Department of Anthropology at Texas A&M University?

• Dr. Emily Johnson

• Dr. Thomas Cody Prang

• Dr. John Smith

• Dr. Michael Brown

What did the researchers compare the shape of the Ardipithecus ramidus hand to?

• Hand specimens from various anthropoid primate species

• Hand specimens from various reptile species

• Hand specimens from various bird species

• Foot specimens from various primate species

What did the researchers find evidence for?

• No significant changes in hand anatomy over time

• A decrease in the use of hands for manipulation in early human relatives

• A big evolutionary 'jump' between the kind of hand represented by Ardi and all later hominin hands

• A decrease in the use of stone tools by early human relatives

What did Charles Darwin propose in 1871?

• The use of the hands and upper limbs for manipulation appeared in early human relatives in connection with upright walking

• The use of the hands and upper limbs for manipulation appeared in early human relatives in connection with swimming

• The use of the hands and upper limbs for manipulation appeared in early human relatives in connection with climbing trees

• The use of the hands and upper limbs for manipulation appeared in early human relatives in connection with running

What does the study support?

• The idea that humans and chimpanzees evolved from an ancestor with flying adaptations

• The idea that humans and chimpanzees did not evolve from a common ancestor

• The idea that humans and chimpanzees evolved from an ancestor with swimming adaptations

• The idea that humans and chimpanzees evolved from an ancestor with suspensory adaptations

What does the big change in hand anatomy between Ardi and all later hominins coincide with?

• The earliest evidence of the use of stone tools and stone cut-marked animal fossils

• The earliest evidence of the use of fire by early human relatives

• The earliest evidence of the use of wheels by early human relatives

• The earliest evidence of the use of metal tools by early human relatives

What does the author propose that the big change in hand anatomy involves?

• The evolution of more advanced running

• The evolution of more advanced upright walking

• The evolution of more advanced climbing

• The evolution of more advanced swimming

What does the fact that Ardipithecus ramidus is such an ancient species potentially help the scientists with?

• Placing the origin of the human lineage into a clearer light

• Placing the origin of the chimpanzee lineage into a clearer light

• Placing the origin of the gorilla lineage into a clearer light

• Placing the origin of the orangutan lineage into a clearer light
