Evolution
What is evolution?
A change over time
What is Natural Selection?
It is when certain species survive in an certain area.
Define the word adaptation (according to your textbook).
An adaptation is a trait shaped by natural selection that increases an organism's reproductive success.
What is Homologous Structure?
Structures that are the same ,but have different functons.
What is Analogous Structure?
Structures that are different but they have the same function
How fast does evolution go through time?
Slow.
How does natural selection impact animals?
Animals go extinct or they become more common based off of this
What is an example of this?
The legs of a human and a dog
What is an example of this?
wings in different birds
Is evolution a random process?
No
Is this a theory? If so who made it?
Yes, it was made by Charles Darwin
Explain the benefit of an animal's ability to be camouflaged within it's environment.
Example of correct answer: By being able to blend in with their surroundings, an animal has a higher chance of surviving; thus leading to a higher chance of being able to reproduce and allow the species to survive.
True or false: Structures that are inherited from a common ancestor are homologous?
True
True or false: Structures that are inherited from a common ancestor are homologous?
False
Does evolution include extinction of other animals?
Yes, they die based off if they are fit for the environment or not
Do natural selection and evolution connect? If so how?
Yes, because evolution is based off of natural selection. Natural Selection is the reason why evolution exists
Explain mimicry, in your own words.
Example of correct answer: One animal evolves to resemble another animal that is higher on the food chain/stronger. This allows the more vulnerable animals to have a higher chance of survival.
fill in the blank: Homologous structures are evidence that _______?
2 species face similar environmental pressures
Fill in the blank: Analogous Structures are evidence that ______?
2 species are not related.
How is evolution a big thing in life through out time
Because the animals adjust to the environment and the animals fitting the environment, survive and they reproduce (Natural Selection)
How many principle does Darwin's Theory of Evolution have?
4
Why is the existence of drug-resistant bacteria a concern?
Example of a correct answer: When bacteria can't be killed by antibiotics, our health is further jeopardized.
Why are they called homologous structures if the structures are different from each other?
Because no matter the structure, they all do the same thing
What is another example of this?
Fins of penguins and fish
