Darwin observed many different species of finches on the Galapagos Islands. What did he conclude about the finches?
They evolved from a common ancestor on the mainland
They evolved from many different types of birds
They all came from different countries and continents
They developed from other types of organisms
Which statement best describes the process of evolution?
Populations can survive in different locations on earth
Environmental conditions limit the number of species on Earth
Populations grow when resources are abundant
The traits of a species can change over time
Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?
Light moths were easy to see against sooty trees and were eaten
Light moths were killed by the soot
The birds that ate the dark moths were killed by the soot
Dark moths were produced by the industrial processes
Modern whales developed their traits through natural selection. What occurs during the process of natural selection?
Organisms choose mates from other species to create new species
Breeders selectively cross organisms with desired traits
Only the fittest organisms can survive and reproduce
Organisms remain exactly the same over time.
Which of these would be considered an adaptation of an animal that lives in the snowy tundra?
A thick coat of fur & blubber
Large, flat feet
Green colored skin
Webbed feet
Which bird is BEST adapted to live in a watery environment?
A bird with short, fat legs and large claws on its feet
A bird with short legs and large webbed feet
A bird with short legs and short skinny toes
A bird with long skinny legs and three thick toes with claws
Which of the items is most likely to be preserved as a fossil?
A flower
Hair or fur
A tooth
Blood
What does the fossil record tell scientists?
Only dinosaurs have formed the fossils scientists have discovered
There are very few organisms that are extinct
Species have evolved over time
Birds have dominated the Earth for most of its history
Over many generation, populations of anteaters have developed longer tongues. Why might such a change occur?
Long tongues help anteaters escape from predators
Anteaters with longer tongues can reach food sources other animals cannot reach
Humans find long tongues more attractive in anteaters
Anteaters with longer tongues require more food than those with shorter tongues
Darwin observed and recorded data about many species of finches. According to Darwin, how did the food source on each island affect how the birds evolved?
Birds brought their favorite food with them to the island
Birds with beaks adapted to the food source on the island survived and reproduced
Birds changed food sources on the island to match their given beaks
Birds ate only certain food sources, causing some foods to survive and others to die
One theory suggests that giant wooly mammoths became extinct when the climate became warmer. Why did this lead to their extinction?
They didn't die off, their traits just changed to match the new climate
There was not enough food available in the warmer climate
Their traits were best suited for a cold climate
Smaller organisms thrived and larger organisms died off when the climate changed.
Organisms with the most beneficial/useful traits live long lives and reproduce. This is called ___________ of the _________.
Survival of the fittests
Benefits of the best
Survival of the living
Survival of the advantageous
In a population of codfish, a scientist notes that some fish have larger or smaller fins than others. These differences among the traits of organisms in a population are known as:
Variation
Extinction
Evolution
Competition
What is the importance of DNA in the human body?
It moves material in and out of the cell
It releases the energy stored in food so it can be used by the body
It carries the genes that determine inherited traits
It's where the proteins are assembled
All of the following are evidence for evolution EXCEPT for:
Similar developmental patterns (embryos)
Homologous structures
Similarities in DNA
Different Genes
Which of the following is the best example of an adaptation that helps an organism survive in its environment?
Green coloring in a lizard that lives on black igneous rocks
A thick waxy cuticle to help store water in a desert plant
a layer of scales on an animal that lives in the tundra
small, delicate leaves on a plant living in the snow
In our bird beak lab, how did the different tools demonstrate adaptations?
It showed how birds can just change their beaks for food
It shows how different beaks were adapted to eat different foods
it showed how birds can eat any type of food
It shows how birds stomachs are shaped like cups
A trait that helps an organism survive and reproduce is called a(n)_____________________
variation
adaptation
species
selection
Darwin's idea about how evolution occurs is called_________
variation
adaptation
natural selection
selection
Whales are closely related to.....
hooved land animals
fish
lizards
sharks
Organisms evolve due to changes in their DNA called________
growing
mutations
cellular respiration
photosynthesis
The evolutionary history of the Earth and its fossil record is incomplete because_________
many organisms don't leave behind fossils, making gaps/missing links
all organisms leave a fossil imprint
Darwin didn't finish writing it
plants don't evolve and don't leave fossils
Evidence for evolution can be found in __________________
comparative anatomy
the fossil record
DNA analysis
All of the above
Which statement that follows was NOT part of Darwin's conclusions?
organisms change over time
evolution is gradual, taking place over a long period of time
evolution takes place over a short time
all organisms are descended from common ancestors
An adaptation is an inherited trait that helps an organism survive.
True
False
Species that share more similarities in their DNA are more closely related than those that share fewer similarities
True
False
Darwin concluded that the mechanism for evolution is Natural Selection
True
False
The process of how organisms acquire adaptations over time is called evolution.
True
False
If variations or diversity is lacking in a population, evolution will not occur.
True
False
Camels having long eyelashes is an example of an adaptation.
True
False
