incorrect
17.
The age of the Earth has been established through the use of _____ ______, in which scientists test for the ____ of parent and daughter elements in a given sample of rock or other material.
A.
A structure in an organism whose original function has been lost during the course of evolution.
B.
A technique for determining the age of objects by measuring the decay of the radioactive elements within them. The age of fossils can be determined with this technique.
C.
The unified evolutionary theory that resulted from the convergence of several lines of biological research between 1937 and 1950.
D.
reproductive advantage; common
E.
Males with longer tails and brighter coloration were more frequently eaten by predator fish; and when males were put in a predator-free environment, brighter coloration and larger tails evolved in them
F.
homologous; common ancestor
G.
common descent with modification; natural selection
H.
1. monkey and trilobite fossils are never found in the same fossil beds 2. DNA sequences of genes shared by various species vary in accordance with predictions about how closely related those species are 3. genetic code is nearly universal
I.
A general set of principles, supported by evidence, that explains some aspect of the natural world
J.
The process through which traits that confer a reproductive advantage to individual organisms grow more common in populations of organisms over successive generations.
K.
Whale flipper, bat wing, and cat forelimb are homologous. Insect leg and octopus tentacles do not belong.
L.
1.) organisms vary in traits that affect their reproduction 2.) descent with modification occurs over generations 3.) traits that confer a reproductive advantage will become more common in populations over time
M.
The process by which species of living things undergo modification in successive generations, with such modifications sometimes resulting in the formation of new, separate species.
N.
All organisms, including humans, are descended from a common ancestor; biological world is constantly evolving; traits found in organisms are the outcomes of a goal-less process; humans occupy one ordinary branch on an enormous tree of life.
