_________ 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
Why could the same species of moth be two different colors?
Their color was based on their DNA. Sometimes a mutation would cause the moth to be born with a different color.
Their color was caused by the environment. The soot from the factories would fuse with the moth's skin.
Bacteria inside the moth's stomach would sometimes give the moth stomach the ability of the moth to have "active camouflouge." This allowed the moths to change their color at will.
If scientists find fossils of a type of mosquito on the bottom layer and find fossils of beetles towards the top layer, what can scientists infer?
Mosquitos ate the beetles
Mosquitos are older fossils than beetles
Beetles are older fossils than mosquitos
Both mosquitos and Beetles must have lived at the same time.
When scientists compare fossils to see about old they are in a certian environment, this is called ____________
Comparing
Absolute Dating
Relative Dating
Comparative Dating
Darwin's ship was called ________
HMS Bugle
HMS Beetle
HMS Asparagus
HMS Beagle
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
Scientists believe horses evolved over a period of 50 million years. How did they change?
They became much larger
Their toes eventually were replaced by a hoof
Their environment changed from a forest to a grassland environment
all the other answers!
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
