What significance did the fossil Lucy have?
She was the oldest fossil found
She was the link between ape and human
She was the smartest ape to live
She was the only ape fossil found in Ethiopia
These limbs provide evidence of common ancestry because they—
The animals in the picture do not live in the same population. They are found in different parts of the world, but are all still part of the camel family. What can be said about these animals?
They belong to the same species
It is difficult for them to find food to eat
They have a very similar skeletal structure
They descended from a common ancestor
According to the cladogram, which organism is most distantly related to the human?
crayfish
grasshopper
perch
frog
Studying which of the following would provide the best evidence that two organisms share a common ancestor?
Amino Acid Sequence
Dietary Preferences
Habitat Requirements
Social Group Interactions
Whales, which live in the water, have hips. These structures are important for carrying the weight of animals that walk on land. Finding this body part in animals that don’t walk on land is best explained how?
Whales have evolved this structure because it might be useful in the future.
Whales are able to interbreed with other animals that have hips.
Whales have a diet that includes other animals that have this structure.
Whales share a common ancestor with animals that walk on land.
The embryos of two different organisms are observed to have similar features. What is the most reasonable conclusion that can be drawn from this observation?
The organisms will share these same features as adults
These organisms will have the same role in the same habitat.
These organisms will take the same amount of time to develop.
These organisms are related by a shared common ancestor.
Studying the embryology of animals provides important evidence to support claims of shared evolutionary history. What feature of embryology makes it capable of providing data for common evolutionary history not readily available from other sources?
As the embryo develops, it reveals the expression of genes
The growth of the embryo is achieved by differentiation of cells.
A developing embryo exhibits structures not present in the adult animal.
The development of embryos of a certain species is consistent.
The collection of fossils and their placement
in chronological order, for example, through
the location of the sedimentary layers in which they are found or through radioactive dating
