Final Jeopardy Category
Survive and Reproduce
Charles Darwin new that organisms had traits and behaviours that allowed them to do what?
A single species or common ancestor
Darwin Argued that all existing species originated from what?
Adapting to their environments
Darwin thought that evolution was the result of organisms doing what?
The origin of species
What was the name of Darwin’s most famous book?
List Lamarck’s 3 assumptions about evolution
What is the only direct evidence of evolution?
What are 3 indirect types of evidence of evolution?
Ear wiggling muscles
What is an example of a vestigial structure in humans?
Embryos of different organisms are the same at early stages of development. This suggest they have come from a common ancestor
How is embryology evidence of evolution?
They show that changes have occurred within organisms, show that organisms have a common ancestor, shows that enough time has passed for evolution to occur
Why are fossils direct evidence of evolution?
Homologous structures show that organisms have a recent common ancestor
Why are homologous structures used as evidence of evolution?
They are structures that no longer have a function
What is a vestigial structure?
Body parts that have a similar structure but have different functions
What are homologous Structures?
Body parts that have different structures but the same function
What are analogous Structures?
It takes time for evolution to occur. It requires people to be born with out the structure and mate with others born with out the structure
Why do some vestigial structures still exist?
Gradual and Punctuated Equilibrium
What are two models of evolution?
It means that the species is in a period where it is not changing because it is suited to its environment
What does equilibrium mean when referring to a species?
A species is in a state of equilibrium for an extended period of time followed by a brief and rapid period of change that produces a new species
Explain Punctuated Equilibrium
It is a model of evolution that is based on slow and steady changes
What is gradualism?
It is the permanent disappearance of a species
What is extinction?
A Double Helix
What is the shape of DNA?
1) Adenine 2) Thymine 3) Cytosine 4) Guanine
What are the four nitrogenous bases of DNA?
What base pairs with Guanine?
Phosphate, Sugar, Nitrogenous Base
What are the three parts of a DNA nucleotide?
Mutations that occur during replication cause the variations that evolution can act on
Why does DNA play and important role in evolution?
Speciation is the creation of new species from a single original species
What is Speciation?
It is the adaptation of structures that perform the same function due to adaptations to similar environments
What is convergent evolution?
It is when one species gives rise to many different species
What is divergent evolution?
What is another name for it?
It is the survival of the fittest. Organisms that have traits that are best suited to an environment survive to reproduce and those traits are then passed on
What is natural selection?
Ancestors, separation of populations, changes in the gene pool, reproductive isolation, sharing the same environment
What are the 5 steps of speciation?
