Adaptation - ANS An inherited characteristic that enhances an organism's survival and
reproduction.
descent with modification - ANS The gradual accumulation of adaptations that
leads to the diversity we see around us today.
artificial selection - ANS a process of selective breeding which occurs only due to
human desires and interventions.
homologies - ANS similar structures due to common ancestry ~ but may have different
function
analogies - ANS similar features not due to a shared common ancestor.
microevolution - ANS the change in allele frequencies in a population over time.
allele - ANS any of the versions of a gene that may produce distinguishable
differences in phenotype
, ©EVERLY 2025 ALL RIGHTS RESERVED
population - ANS a group of individuals of the same species living in the same area and
interbreeding.
mutation - ANS a change in the nucleotide sequence of an organism's DNA
gene pool - ANS every type of allele at every locus in all members of the population
macroevolution - ANS Broad pattern of evolution above the species level
autopolyploid - ANS an individual that has more than two chromosome sets from
a single species. In plants they can produce fertile offspring by self fertilization
reinforcement - ANS possible outcome for hybrids, strengthening of reproductive barriers
stability - ANS possible outcome for hybrids, continued productions of hybrid individuals.
Fusion - ANS possible outcome for hybrids, weakening of reproductive barriers
protocells - ANS aggregates of abiotically produced molecules surrounded by a membrane or
membrane-like structure
endosymbiont - ANS a cell that lives within a host cell
Hadean Eon - ANS Formation of earth, first life may have appeared here. (4.5- 4 billion years
ago). SINGLE CELLED LIFE
Protozeroic Eon - ANS Eukaryotes appear. Soft bodied invertebrates become common. (2.5 -
.5 billion years ago). Finally, MULTICELLULAR LIFE, and around 800 million years ago, animals
