Scientists
The name of the islands that Charles Darwin was most interested in studying
Galapagos Islands
When an organism had more offspring than they need
overproduction
this is a form of a gene
allele
These are structures that no longer serve a function, but did function in a common ancestor.
Vestigial structure
Charles Darwin is famous for studying this animal
Finches, Tortoises
Name one of the 2 ways variation can occur
Mutations, sexual reproduction
consist of all the genes, including the different alleles for each gene, that are present in a population
gene pool
What do scientists look at when using comparative biochemistry?
DNA
Explain Lamarck's Theory of evolution
Whatever changes occur during your lifetime, you pass onto your kids
Name 3 things an organism might have to compete for
food, water, shelter, territory, mates, etc.........
A sudden change in the environment (ex: natural disaster) that may drastically reduce the size of a population
bottleneck effect
Similar structures that have been inherited from a common ancestor, regardless of use (swim, fly, etc.)
Homologous structures
The name of the scientist who disproved Lamarck's theory of evolution
Karl Weismann
What physical characteristic do the Galapagos Finches have that make them specialized for their islands?
Beaks
Occurs when a few individuals become isolated from a larger population
founder effect
Serve a similar purpose (ex. Flying) but evolved independently from one another.
Analogous structures
The name of the theory that Jean Lamarck came up with for Evolution
Theory of Use and Disuse
Tell me the difference between the word ADAPT and ADAPTATIONS
Populations ADAPT, individuals have ADAPTATIONS
What are 2 things that would have to occur in order for evolution to stop
no mutations, random mating, no migration, large populations, no natural selection
Scientists use several types of evidence to determine relationships. We talked about 4 types, give me 3 of those 4
Comparative embryology, comparative cytology, comparative anatomy, Comparative biochemistry
