Biology Evolution Flashcards
Evolution
A gradual change of inherited
characteristics, over time
Natural selection
A process by which a species
changes over time, in response to
changes in the environment, in
order for the species to survive.
The members of the species with
the most desirable characteristics
are able to produce the best-
adapted offspring
Variation
Differences between individuals of
the same species
Antibiotics
Substances that slow down or
stop the growth of bacteria
Antibiotic
resistant
Bacteria which are not affected by
an antibiotic, usually due to a
gene mutation
Mutation
A change in a gene or
chromosome
Fossils
Preserved remains of dead organisms
Stratigraphy
A method of dating items based
on the age of the layer of rock
they are found in
Carbon dating
A method of dating organic
materials
Classification
Sorting organisms into groups
based on their similarities and
differences
Binomial naming
The binomial name of a species
has two parts: (1) the genus
name and (2) the species name
Genetic
analysis-
The study of a sample of DNA to
look for similarities and mutations
(changes).
