What was Redi's experiment?
He did an experiment with flies and wide.
100
What was Darwin's idea?
The different species have to change over time.
100
Where are the elder fossils?
at the bottom.
100
What is biogeography?
the study of the distribution of species and ecosystems in geographic space and through geological time.
100
What is the absolute age of a fossil?
Absolute age is the age of a fossil as determined by the measurement of radioactive decay from the time of the fossil's formation.
200
What did people know from Redi's experiment?
The meats were not come from the jars.
200
What is the similar point of Lamarck and Darwin?
They both had been on sea voyages.
200
Why do we learn about fossils?
Fossils give us information from the past.
200
What did Darwin find out while he observed the animals? (about biogeography)
lots of the animals look similar even they live far apart.
200
Give two examples of natural selection.
Overproduction, Genetic Variation, struggles of living...
300
Pasteur's experiment was better than Spallanzani's experiment, why?
Pasteur used different shape of flask and he made sure that each of them could touch the air.
300
Give an example of overproduction.
Each female deer has one or more offspring per year for many years in a life time. (no exact answer)
300
How did scientists compare the age of fossils?
They use the relative(absolute) age of fossils.
300
Different animals have different habits, what do you think to cause it?
the adaption of the animals.
300
What is phylogeny ?
the study of evolutionary relationships among groups of organisms.
400
What did we learn from Pasteur's experiment?
The dust is came from the air.
400
How did Darwin think about Natural selection?
He proposed the theory of natural selection as the mechanism for descent with modification.
400
What's the different between the younger fossils and the elder's?
The younger fossils are more similar to the modern living things than the elder's.
400
Why is the biogeography important to distribute？
It tells us how the environment effects the animals and why the animals in different get similar shape. (no exact answer)
400
What is evolution?
It's the development of new types of organisms from preexisting types of organism over time.
500
What is the main idea of these scientists' experiments?
The living things are not came from the nonliving things, the spontaneous generation is ridiculous.
500
How does adaption so important to animals?
They have adaption so that they could live in different environments.
500
What could we get from fossils?
DNA from the past living things, information about the past living things like dinosaurs.
500
Who are the first scientists to study the biogeography?
Darwin and Russel Wallace.
500
What is half-life?
The amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.
