Different species adapt to similar environments & unrelated species evolve similar structures.

convergent evolution leads to analogous structures

What is NOT one of the observations that Darwin made before formulating his theory of evolution

similarities in the DNA sequences of related species

closely related species evolve in different environments to have different structures.

divergent evolution leads to homologous structures

divergent evolution leads to analogous structures
divergent evolution leads to homologous structures
convergent evolution leads to analogous structures
convergent evolution leads to homologous structures
2
The change in allele frequency due to chance is called
bottle ring effect
finder effect
genetic drift
genetic jump
3
This kind of selection results from humans choosing/breeding organisms with desirable traits
artificial selection
stabilizing selection
disruptive selection
directional selection
4
Natural selection can act on populations by selecting against one extreme of a trait. This is
directional selection
disruptive selection
stabilizing selection
artificial selection
5
What is NOT one of the observations that Darwin made before formulating his theory of evolution
geologic evidence
differences among species on different islands
the fossil record
similarities in the DNA sequences of related species
6
The process when two or more species evolve in response to each other.
bievolution
revolution
coevolution
de-evolution
7
Natural selection can act on populations by selecting against both extremes of a trait. This is
called directional selection
called disruptive selection
artificial selection
called stabilizing selection
8
genetic drift that occurs after a small number of individuals colonize a new area is called...
finder effect
bottleneck effect
founder effect
founder affect
9
Who is credited for formulating the theory of evolution?
Einstein
Darwin
Lyell
Mendel
10
What is NOT true about evolution?
Natural selection acts on pre-existing genetic variation
Evolution works on populations not individuals
humans evolved from apes
Small changes usually happen over millions of years
11
What is NOT evidence of Evolution?
homologous structures
fossils
analogous structures
embryology
12
The movement of alleles (different versions of a gene) from one population to another is called
gene flow
gene change
allele flow
gene flight
13
Reproductive isolation can lead to speciation. Which is NOT a type of reproductive isolation
geographic isolation
solitary isolation
temporal isolation
behavioral isolation
14
The diversification of one ancestral species into many descendent species is called...
nuclear radiation
adaptive radiation
adaptive rotation
adaptive response
15
What is evolution in terms of biology?
Change of a species over time
Individuals evolve to suit their environment
something that only happend in the past
organisms intentionally changing to survive
16
closely related species evolve in different environments to have different structures.
divergent evolution leads to analogous structures
divergent evolution leads to homologous structures
Convergent evolution leads to homologous structures
Convergent evolution leads to analogous structures
17
Who developed the theory of endosymbiosis?
Mendel
Lynn Margulis
Lyell
Darwin
18
What are the four main principles of the theory of natural selection
variation,underproduction,adaptation,descent w/ modification
variation,overproduction,adaptation,descent w/ modification
variation,overproduction,conception,descent w/ modification
evasion,overproduction,adaptation,descent w/ modification
19
What is NOT evidence for the theory of endosymbiosis?
mitochondria and chloroplasts can live outside of a cell
mitochondria and chloroplasts can copy themselves
mitochondrial & chloroplast DNA is circular like prokaryotes
mitochondria & chloroplasts have their own DNA & ribosomes
20
Natural selection can act on populations by selecting against the average of a trait. This is
disruptive selection
artificial selection
directional selection
stabilizing selection
