Chp.1
The process by which organisms have descended from ancient organisms is called...
Evolution!
A mechanism is...
Fitness...
describes how well an organism can survive and reproduce in its environment.
What's microevolution?
What does LUCA stand for?
Last Universal Common Ancestor.
a group of similar organisms that mate with each other and reproduce offspring?
species.
What's natural selection?
A process by which individuals that are better adapted are more likely to survive and reproduce.
Name one way mutations can happen.
Either DNA is making an error while making copies, or environmental factors can cause variation.
What gives more information about appearance: body or trace fossils?
Body fossils.
What type of organism was LUCA most likely: single-celled, plant, or animal?
Who was the first to try to explain evolution? (double if you get the first name)
Jean-Baptiste Lamarck.
What are the three factors of natural selection?
Overproduction, variation, and competition.
False.
What gives more information about how the animals lived: body fossils or trace fossils?
Trace fossils.
What's endosymbiosis?
One organism lives in another from a different species.
What did Mary Anning do?
She searched for fossils to make money. She was important for realizing that there were extinct animals.
What is artificial selection?
Individuals witrh a desired trait are breeded by humans.
Does gene flow increase or decrease genetic variation?
Increases.
The structure of an organism's body is called its...
anatomy.
Does gene transfer apply to parents giving genes to children?
No.
A person who observes and studies the natural world is a...
naturalist.
What is competition?
(keyword needed)
the STRUGGLE among living things to get necessary food, water, and shelter.
Is gene flow or genetic drift random, or both?
genetic drift ONLY.
Does microevolution or macroevolution lead to more deaths?
Macroevolution.
What two are more likely in the mutation of a protein: helping fitness, harming fitness, or doing nothing to the organism's fitness?
harming and nothing.
