evolution - CORRECT ANSWER✔✔-"glue that unites everything together
| | | | | | |
in bio"
| |
- change in populations over time (generations
| | | | | |
What are the four principal requirements of evolution by natural
| | | | | | | | | |
selection? - CORRECT ANSWER✔✔-1. variation
| | | |
2. fitness differences
| |
3. inheritance
|
4. more offspring produced than can surive
| | | | | |
variation - CORRECT ANSWER✔✔-differences between individuals in
| | | | | | |
population with a specific character or trait
| | | | | |
fitness differences - CORRECT ANSWER✔✔-differences in individuals in
| | | | | | | |
the ability to survive and reproduce
| | | | |
inheritance - CORRECT ANSWER✔✔-passed on from parents to
| | | | | | | |
offspring (good traits) | |
,How did John Endler test the hypothesis that color patterns in guppies
| | | | | | | | | | | |
represent a trade-off | |
between selection to avoid predation and selection to attract a mate? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-stocked ponds with guppies each with color
| | | | | | | |
variation, manipulated predation subsrate of gravel, and took a censure
| | | | | | | | | |
of them at five months and fourteen months.
| | | | | | |
Why is natural selection not simply a matter of chance? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-it selects phenotypes and genotypes that are best suited | | | | | | | | |
for the environment
| |
What is an adaptation? - CORRECT ANSWER✔✔-a trait or characteristic
| | | | | | | | | |
which fosters the survival/ reproduction of an individual within a
| | | | | | | | | |
particular environment |
What kinds of testable predictions can be derived from the theory of
| | | | | | | | | | | |
evolution as it applies to | | | |
the fossil record? - CORRECT ANSWER✔✔-1. if evolution occured,
| | | | | | | | |
species that lived in past should be dif from extant species
| | | | | | | | | |
2. simple life should be found in oldest strata, more complex forms in
| | | | | | | | | | | | |
only recent strata
| |
-relative time scale based on geological comumn
| | | | | |
, How do direct observations of natural populations provide evidence of
| | | | | | | | | |
change
over time? - CORRECT ANSWER✔✔-example; guppie example endler
| | | | | | | |
saw how they changed through their enviornment, since they have
| | | | | | | | | |
short generation times, it was still a year and two months (14 months),
| | | | | | | | | | | | |
it didnt change over night
| | | |
What is homology? - CORRECT ANSWER✔✔-similarity due to common
| | | | | | | | |
ancestry
- theories must make testable predictions
| | | | |
- predicitions must be falsifiable
| | | |
What kinds of testable predictions can be derived from the theory of
| | | | | | | | | | |
evolution as they apply to homologies at all levels of biological
| | | | | | | | | | |
organization: structural, |
embryonic, cellular and molecular? - CORRECT ANSWER✔✔-if in same
| | | | | | | | |
homology, all of it will be similar in some way. if not exactly but close.
| | | | | | | | | | | | | |
How do changes observed in the beak morphology of medium ground
| | | | | | | | | | |
finches over the last 20 | | | |
years conform to the criteria for evolution by natural selection? -
| | | | | | | | | | |
CORRECT ANSWER✔✔-Because there was a drought that caused only
| | | | | | | | |
big seeds to remain and birds with big beaks able to crack open the
| | | | | | | | | | | | | |
seeds survived and reproduced.
