Fossil records show that the early genus Ardipithicus ramidus (Ardi) had long arms and curled big toes. What does this suggest?They had a small brainThey had a mainly vegetarian dietThey spent time in treesThey used tools2Which of these statements about the fossil called Lucy is not true?Her toes were less curled than Ardi’sShe walked in an upright position but had a small skullShe dates from 4.4 million years ago.She was one metre tall3During human evolution, which of the following trends was not seen?Brains grew largerArms became longerHeight increasedIncreased use of tools4Which of the following statements about tools as evidence of human evolution is not true?The development of more advanced tools can be linked to an increase in brain sizeTools became more advanced over timeStone tools have been found that date back to the early genus ArdiTools can be dated by radiocarbon dating of the elements in the rocks found around them

What is known about the "Ardi" skeleton

A scientist is studying three different layers of sedimentary rock to learn how a particular mammal species has changed over time. In the rock layer that is closest to the Earth's surface, fossilized individuals of this species have hooves on both their front feet and their back feet. In the layer below, fossilized individuals have three padded toes on both their front feet and their back feet. In the bottom layer, fossilized individuals have four padded toes on their front feet and three padded toes on their back feet.Based on this information, individuals of this species today most likely have A. four padded toes on their front feet and three padded toes on their back feet. B. hooves on both their front feet and their back feet. C. three padded toes on both their front feet and their back feet. D. four padded toes on both their front feet and their back feet.

While researching a topic, a student has taken the following notes:The arthropod phylum encompasses cockroaches, crabs, butterflies, centipedes, scorpions, lobsters, and termites, among other creatures.The distinguishing characteristics of arthropods are a jointed skeletal covering (an exoskeleton) and a segmented body.Recently, scientist Sara Losso at Harvard University found an impeccably preserved arthropod fossil.The fossil was of a curled up arthropod, demonstrating an important arthropod survival tactic.In the Peleozoic Era, ancient arthropods curled up like armadillos to avoid danger on the seafloor.The student wants to emphasize the fossil’s significance. Which choice most effectively uses relevant information from the notes to accomplish this goal?The fossil Sara Losso found is an example of an arthropod, a creature with an exoskeleton and a segmented body. eliminateSara Losso of Harvard University recently found an impeccably preserved arthropod fossil. eliminateSara Losso’s well-preserved arthropod fossil illustrates a survival method of ancient arthropods, wherein they curled up.eliminateCockroaches, crabs, butterflies, and other arthropods have ancestors as old as the Peleozoic Era.
