What do we call a change in a species over time?
Adaptation
Evolution
Extinction
Environmental influences
_________ is the process of change by which species of organism change over time.
Nucleotides
Evolution
Mutation
Carbon
Birds are eating all the green beetles. Because the brown beetles are surviving they reproduce more and make more brown beetles. This is called ___________
Artificial Selection
The Theory on the Origin of Species
Natural Selection
Mutation
Darwin wrote that the organisms best suited to their environments will .....
Increase in Number
Go Extinct
Mutate More often
Which trait did Darwin pay most attention to about the finches in the galapagos islands?
Their Feathers
Their Horns
Their Size
Their Beak Shape
Why were the beaks on Darwin's finches so Important?
They showed the finches always existed as Darwin found them.
They showed that the finches could mutate their beaks whenever they want.
They showed variability in the finches species. All finches were equally adaptable to all islands.
They show that the finches adapted to their environments. Their beak shape matched the food available on each island.
4. When the industrial revolution started, the trees have been covered in soot from coal factories. Which moth will be more successful in this environment?
White Moth
Dark Moth
Both are Equally Successful in this Environment
Which of the following do scientists not use as evidence for evolution?
Fossils
Vestigial Structures
Embryology
Radiation
When we examine this whale fossil, we can see that the whale has a pelvic bone that doesn't seem to be used by the whale. What do scientists infer?
The whale had an ancestor with legs
The whale must use the pelvis for an unknown reason
The whale was born with an extra bone and has a disorder
The whale had an ancestor with wings
In evolution, these are body parts of species that have similar features.
Adaptable features
Vestigial Structures
Nucleal Structures
Homologous Structures
Why are homologous structures important to the theory of evolution?
Scientists use them as evidence that many species must have had a common ancestor.
Scientists use them as evidence that many species must have independently evolved and are not related to other species.
Scientists use them as evidence to show that all kinds of structures in our bodies work to help us survive.
Why are vestigial structures evidence for evolution?
They are useful in the organism and show natural selection at work.
They are not useful in the organism but they were probably useful in some ancestor of that species.
They show that these organs or behaviors help an organism adapt to new environments
How do scientists use embryology to support the theory of evolution?
Embryos of many species have a lot of similar characteristics when they are first forming showing different creatures must have a common ancestor
Embryos of many species have very little in common until they start developing for long periods of time
Features like gills and tails prove that all animals are really just fish
have the ability to interbreed.
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the organism knew it needed that trait, survives, and passes it on.
Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
changes in genotype, but not phenotype
Why is competition important for natural selection?
It shows which variations are more successful, allowing the organisms with those variations to survive.
It causes organisms, regardless of which traits they have, to die out, reducing the population size.
It causes organisms to get stronger due to having to outcompete other species.
Competition is not important for natural selection.
According to the diagram, what is the common ancestor of ALL organisms on the phylogenetic tree?
B
C
D
E
Using the diagram, is organism 4 MORE closely related to organism 3 or 5?
3
5
Who is most closely related to Taxidea taxus?
Lutra lutra
Panthera pardus
Canis latrans
Canis lupus
According to the cladogram, which organism is most distantly related to the human?
crayfish
grasshopper
perch
frog
In a phylogenetic tree, the branching points represent common ancestors.
Yes
NO
The lizard has all these derived characteristics EXCEPT
Jaws
Lungs
Bipedal
behavioral isolation
temporal isolation
gametic isolation
geographic isolation
Direct evidence of speciation is when interbreeding to produce viable and fertile offspring is no longer possible. This is known as _ isolation.
(a)
Artificial selection is...
the process by which humans determine which traits to pass on and which traits to eliminate based upon breeding.
the process by which natures selects who lives and dies.
the process by which animals adapt to their surroundings.
the process by which people take over ecosystems.
Organisms with the most beneficial traits will survive and reproduce. This is commonly known as ______.
DNA
variations.
fitness.
ecosystems.
A herd of elephants uses their trunks to get food more than another heard. Since they are using their trunks so much they get longer and stronger. Then those elephants pass on long strong trunk genes to their kids because they used them so much. Whose idea is this and is it right or wrong?
Lemark; wrong
Lemark; right
Darwin; wrong
Darwin; right
