According to Linnaean taxonomy, what is the MOST specific category and level shared by humans, gorillas, and howler monkeys?
Darwin did not know about genes but believed that traits passed from parents to offspring by particles called
Darwin studied species of ____________ in the ____________ Islands when coming up with his ideas about evolution.
Darwin’s ideas about evolution and Mendel’s research in genetics are combined into what we now call the idea of blending inheritance.
Darwin’s ideas helped stimulate research in the fields of biology, genetics, comparative anatomy, and physical anthropology.
In a simplified example of eye color inheritance, B stands for the allele for brown eyes and is dominant. Blue eyes are represented by the recessive allele b. A child who inherits one of each allele from her parents will have the genotype Bb and therefore have brown eyes.
In the evolutionary synthesis, Mendel’s theory indicates how traits are passed from one generation to the next, while mutation explains where variation originates.
James Hutton disagreed with biblical estimations of Earth’s age. In contrast to biblical estimates of a few thousand years, Hutton estimated that Earth was several million years old.

This animal was instrumental to Linnaeus’s creation of binomial nomenclature.
This picture shows two variants in ___________ or physical appearance of seven characteristics of the pea plant.

While home for winter break, you start telling your grandmother about your physical anthropology class. She once heard about a man who became a bodybuilder and then produced muscular children, and she asks you to explain how this could happen. What correct information could you give her?
This is an example of Lamarckism, which has some kernels of truth about evolution but is not a wholly accurate theory.
Who was the naturalist who spent five years on the HMS Beagle?
Your history professor is interested in genealogy and tells your class that, on his mother’s side, he is descended from the original Amish population, a religious and insular group of people in Pennsylvania who tended to marry within their social circle. He also notes that many members of his extended family have the condition polydactyly, an extra finger or toe. The high frequency of polydactyly in your professor’s ancestry is an example of _________________ in the Pennsylvania Amish.
