The Galapagos Islands are where Charles Darwin:
Wrote "On the Origin of Species"
studied unusual animals such as tortoises, finches and iguana's
was exiled after his theories were proven unpopular
was born and raised
The beaks of finches found on various Galapagos Islands differed based on:
size of the island
length of their wings
what was available for food
the predator that hunted them
What is a common ancestor?
an animal that has a lot of offspring (babies)
an animal from which 2 or more species evolved
an animal that is related to many other species
an animal that is good at escaping from predators
What is least likely to be an example of a variation within a species?
birth weight
hair color
number of offspring (babies)
number of limbs (ex: hands & feet, paws)
Which of the following is an example of an environmental pressure?
air pressure in the atmosphere
breeding between two members of the same species
a lake that gradually running out of water
a flight between 2 members of the same species
In the phrase "survival of the fittest," the term "fittest" refers to:
the biggest organisms
the best adapted organisms
the best smartest organisms
the best fastest organisms
Which variation would be most likely to benefit any organism, regardless of environment?
The ability to produce energy more efficiently.
The ability to swim deeper.
Bigger claws and teeth.
Markings that it blend into its background.
When nature "selects" a variation, that means that the trait:
causes the population to shrink
helps prey escape predators
gets passed long from generation to generation
has brought out a new species
Dogs are an example of:
common ancestor
selective breeding
extinction rates rising
the natural pace of evolution
On Darwin's tree of life, organisms at the base of a branch
go extinct from environmental pressures
evolve into the closest species on the tree's trunk
give rise to species farther down the branch
are less fit than species in the middle of a branch
