Prior to the work of Lyell and Darwin, the prevailing belief was that

A farmer uses triazine herbicide to control pigweed in his field. For the
| | | | | | | | | | | | |
first few years, the triazine works well and almost all the pigweed dies;
| | | | | | | | | | | | |
but after several years, the farmer sees more and more pigweed. Which
| | | | | | | | | | | |
of these statements explains why the pigweed reappeared?
| | | | | | |
(a) The herbicide company lost its triazine formula and started selling
| | | | | | | | | | |
poor-quality triazine. |
,(b) Natural Selection caused the pigweed to mutate, creating a new
| | | | | | | | | | |
triazine-resistant species | |
(c) Triazine-resistant pigweed has less-efficient photosynthesis
| | | | | |
metabolism
(d) Triazine-resistant weeds were more likely to survive and reproduce. -
| | | | | | | | | |
CORRECT ANSWER✔✔-(d) Triazine-resistant weeds were more likely to
| | | | | | | | |
survive and reproduce.
| |
Gradualism: - CORRECT ANSWER✔✔-an idea that states geologic
| | | | | | | |
processes happen very slowly (i.e. sea level flux, erosion)
| | | | | | | |
artificial selection - CORRECT ANSWER✔✔-selection guided by humans
| | | | | | |
Acquired - CORRECT ANSWER✔✔-the type of trait that cannot be
| | | | | | | | | |
passed on genetically (think of our favorite meat monster, Dwayne "The
| | | | | | | | | | |
Rock" "Rocky" "DJ" "Flex Kavana" "The Brahma Bull" "The People's
| | | | | | | | | |
Champion" "Dewey" Johnson and his big muscles and what his kid
| | | | | | | | | | |
might look like)

Homologies - CORRECT ANSWER✔✔-anatomical traits that are a result
| | | | | | | | |
of common ancestry
| |
Natural Selection - CORRECT ANSWER✔✔-The mechanism of evolution.
| | | | | | | |
The only mechanism for changes in allele frequency that ALWAYS results
| | | | | | | | | |
in adaptive evolution
| | |
Scala Naturae - CORRECT ANSWER✔✔-An attempt by Aristotle to
| | | | | | | | |
organize life on Earth. | | |
Populations - CORRECT ANSWER✔✔-The smallest unit of selection
| | | | | | |
Intron - CORRECT ANSWER✔✔-Part of DNA that does NOT leave the
| | | | | | | | | | |
nucleus when mRNA is completed
| | | |
Genetic Drift - CORRECT ANSWER✔✔-the mechanism responsible for
| | | | | | | |
there being waaaaay too many nipples on Tristan de Cunha (at least
| | | | | | | | | | | |
compared to mainland populations)
| | |
Hybrid Zone - CORRECT ANSWER✔✔-
