Q1: evolution
A: decent with modification; change in in genetic composition of a population from
generation to generation
Q2: fossils
A: the remains or traces of organisms from the past
Q3: strata (stratum= singular)
A: superimposed layers of rock
Q4: paleontology
A: study of fossils developed by Cuvier
Q5: adaptations
A: inherited characteristics of organisms that enhance their survival and reproduction in
specific enviroments
Q6: natural selection
A: process in which individuals that have certain inherited traits tend to survive and
reproduce at a higher rates than other individuals because of those traits
Q7: artificial selection
A: modified species over many generations by selecting and breeding individuals that
possess desired traits
Q8: homology
A: similarity resulting from common ancestry
Q9: homologous structures
A: Structures in different species that are similar because of common ancestry.
, Q10: vestigial structures
A: remnants of features that served a function in the organisms ancestors
Q11: convergent evolution
A: independent evolution of similar features in different lineages
Q12: analogous
A: species share features because of convergent evolution
Q13: biogeography
A: scientific study of geographic distributions of species
Q14: Pangaea
A: all the continents combined 250 million years ago
Q15: microevolution
A: evolutionary change in populations on smallest scale
Q16: genetic variation
A: variation among individuals in the composition of their genes or other DNA sequences
Q17: neutral variation
A: differences in DNA sequence that do not confer a selective advantage or disadvantage
Q18: population
A: group of individuals of the same species that live in the same area and interbreed
producing fertile offspring
Q19: gene pool
A: consists of all copies of every type of allele at every locus in all members of a population
