Evolution

QuestionAnswer
What is evolution? The change in living things over time
What did Darwin do on the Voyage of the Beagle? He was the ship scientist
What's the deal with the Galapagos finches? They all had beak's that were adapted to the food they ate
What do we call natural differences in traits between members of the same species? VARIATIONS
What do we call it when one species adapts to look like another species? MIMICRY
When organisms evolve to blend in with their environment we call it CAMOUFLAGE
What is Natural Selection? When organisms that have traits that are best suited to their environment are more likely to survive and pass on genes
What is Artificial Selection? When human beings select traits in either plants or animals that we want to continue and only breed those indiviuals
What does Survival of the Fittest means? It means that individuals who have traits most suited to their environment will be the ones to survive and reproduce
What is overproduction? It is when a species is producing more offspring than can realistically survive to adulthood
What are some things that species would compete for? Food, water, sunlight, mates, space, shelter
What is a fossil? Any evidence of an organism that lived long ago
How can we use the idea of Relative Dating to figure out how old a fossil is? The oldest fossils would be at the bottom of a rock sample and the youngest would be at the top
What type of rock is most likely to have fossils in it? SEDIMENTARY
What do we call body parts that are structurally similar in related species? Homologous structures
If several species look very similar in their embryo stage this indicates........ they come from a common ancestor
How did Aristotle group things? By how they moved around
What is taxonomy? The science of naming and classifying living things
What is the largest classification level? ( has the most members) DOMAIN
What is the smallest classification level? ( has the least members) species
Who invented Binomial Nomenclature? Carolus Linnaeus
How do we correctly write the Genus and Species? Capitalize the Genus. The species is written lowercase. Both should be underlined or in italics.
Why do some mutations continue on in a population while others are eliminated? Because some mutations cause a variation that gives the individual who has it an advantage in his/her environment. With an advantage he/she is more likely to SURVIVE AND REPRODUCE thereby passing on the variation!!!!
True/False: The strongest individuals always survive. FALSE!!!!! THE SURVIVORS ARE THE INDIVIDUALS THAT ARE BEST SUITED TO THEIR ENVIRONMENT!
Explain how a variation can become an adaptation. Those who are born with a variation that gives them an advantage in their environment will be more likely to SURVIVE AND PASS ON THEIR GENES. Over time, more individuals will be born with the variation until all members of the populations have it.
