Bio 182 Exam 1
Common Descent - CORRECT ANSWER-principle that all living things were derived
from common ancestors
Natural Selection - CORRECT ANSWER-Differential reproductive success of individuals
of a population, due to inherited differences between them. IE Some individuals have
lots of strong traits or adaptations, that allow them to live longer and mate more.
What is the result of Natural Selection? - CORRECT ANSWER-Evolution
Evolution - CORRECT ANSWER-a change in the allele frequencies in a population over
an extended period of time.
Homology - CORRECT ANSWER-Similarity in characteristics resulting from a shared
ancestry.
Biogeography - CORRECT ANSWER-dealing with the geographical distribution of
animals and plants
Comparative Anatomy - CORRECT ANSWER-The comparison of body structures and
how they vary among species
Karyotype - CORRECT ANSWER-A picture of all the chromosomes in a cell arranged in
pairs
Fossils - CORRECT ANSWER-works because of the formation of sedimentary rocks.
Best fossils come from ocean sediments.
Scientific Theory - CORRECT ANSWER-A broad explanation that has been subjected
to a lot of testing, that reliably gives up accurate predictions.
A Theory tells you why something is true
Scientific Theory - CORRECT ANSWER-1. Helps explain the why of things that we
already know to be true.
2. Reveals connections between known facts that are not already known to be true.
3. Allows to accurately predict new facts (most important)
