Humans, birds, whales and lizards all have similar arm bones. What do evolutionists consider is the reason for this?
The function of these bones is the same in all animals
They live in similar environments
They have a common ancestor
All organisms resemble humans
The process by which populations slowly change over time is called__________
selective breeding
adaptation
sepeciation
evolution
From an evolutionary perspective, organisms that share a common ancestor have structures that are similar, but have different functions.These similar structures are known as
vestigial structures
analogous structures
homologous structures
fossil structures
The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct from the evolutionary perspective?
Fossil A and C are the same age
Fossil B is older than fossil C
Fossils A is older than fossil B
Fossil D is older than fossil C
An inherited trait that helps the organisms that have it to survive is known as a/an
niche
structure
characteristic
adaptation

The human gene for muscle protein differs from the muscle protein in monkeys in 4 places. It differs from chickens in 25 places. According to this information, which organism is more closely related to humans?
Monkeys are more closely related because their proteins have fewer differences.
Chickens are closer to humans because there are more genes.
Monkeys are closer to humans because they both have the exact same genes.
Neither organism is related to humans.
