Who is Charles Darwin?
studied finches on the Galapagos Islands and developed the theory of natural selection based on his observations of speciation between the different bird types genetic variation is the key mechanism; “survival of the fittest”; supported by several categories of evidence
the first scientist to propose a theory of evolution; believed that organisms could “try” to evolve (ex: giraffes wanted to reach leaves at the tops of trees, so their necks grew); no longer supported by genetic evidence
a structure that is no longer used by an organism and is often small in size - evidence of possible past structures
states that allele and genotype frequencies in a population
will remain constant from generation to generation in the absence of other evolutionary influences.
Natural selection is..?
humans choose characteristics of organisms that they want to
continue in future generations; also called selective breeding (ex: dog breeds)
a change or the process of change by which an organism or species becomes better suited to its environment.
Darwin’s theory stating that certain genes in a population are more
favorable than others for survival, which will allow them to be passed to future generations and cause an overall change in the population with time (“Survival of the Fittest”)
the formation of a new species due to the process of evolution
