Who is Charles Darwin |
An individual who contribute more to our understandings of evolution than anyone else |
|
|
What is speciation |
Species to evolve into two new species |
|
|
What was the difference between the finches birds found on the Galapagos Islands |
If they had different features but the same bird like beaks example long thin big short thick feet |
|
|
What was Jean Baptiste limericks theory of evolution |
If an organism did not use a specific trait over time it will lose it |
|
|
What is inheritance of acquired traits |
traits that can be passed on to their offspring overtime leads to a change in a species |
|
|
How does comparative embryology help support Darwin's theory of evolution |
Shows that in the earliest stages of embryos development many animals with backbones are very similar |
|
|
What are homologous structures and how do they support Darwin's theory of evolution |
Structures that have different mature forms but develop from the same embryonic tissue |
|
|
The survival of the fittest is the common term for Darwin's theory of evolution what is his theory called |
Darwin's theory of natural selection |
|
|
What is selective breeding or artificial selection |
Humans pick what traits get passed on by selecting which organisms reproduce |
|
|
What are fossils and how do they support the theory of evolution |
Fossils are imprints what element that take a long time to make the impression that's how it supports the theory of evolution |
|
|
Is evolution still continuing today give me an example |
Yes evolution is still continuing to today and example is called bacteria musrsia |
|
|
What is choosing specific traits to be passed on from generation to generation |
Artificial or selective breeding |
|
|
What is a theory |
I think that is not proven but is supported well by science |
|
|
What does Hardy Weinberg principal say |
Allele frequencies will remain constant unless one or more factors cause change |
|
|
What is the founder effect |
A migration of a small group of a population |
|
|
What are three of the forms of evidence supported Darwin's theory of evolution |
Fossil record genetics Age of the earth |
|
|
What are the different kinds of reproductive isolation |
Behavioral isolation different cord courtship rituals or other reproductive side edges geographic isolation separated by geographic boundaries temporal isolation reproduction at different times |
|
|
What is fitness |
Ability of an individual to survive and reproduce in its specific environment |
|
|
Does the environment affect the frequencies of different traits in a population |
Yes |
|
|
Order of the process in oldest to newest |
Natural selection artificial / selective. breeding gene manipulation |
|
|
Would a population with a ton of variety or little variety will have a greater chance of going extinct if the environment changed |
The population what little variety would have a greater chance of being extinct |
|
|
What is genetic drift |
A small group that leaves a bigger group and reproduces and looks like they evolved but they didn't |
|
|
What are the four postulates of Darwin's theory of evolution |
1 there is a variation in a population Two more organisms are born that survive to reproduce 3 those organisms that have an advantage over those that don't survive For some of those advantages are haritable |
