Charles Darwin proposed the theory of evolution with 2 main points... which are?
|
1. Descent with Modification (Evolution)
2. Natural Selection as a mode of Evolution |
In Darwin’s Origin of Species
|
|
______ is the process by which favorable heritable traits become more common in successive generations of a population of reproducing organisms, and unfavorable heritable traits become less common.
|
NATURAL SELECTION
|
Differential Reproductive Success
|
|
_______is a positive characteristic of an organism that has been favored by natural selection. Changes over time to favor said trait.
|
ADAPTATIONS
|
Result of Natural Selection
|
|
________is the intentional breeding for certain traits, or combinations of traits, over others.
|
ARTIFICIAL SELECTION
|

Bell Curves
|
|
Similarity in characteristics resulting from common ancestry is known as _______
|
HOMOLOGY
|
1. Anatomical (Homologous Structures)
2. Molecular (esp. DNA) 3. Embryological- developmental structures and processes. |
|
______ is the process whereby organisms not closely related and independently evolve similar traits as a result of having to adapt to ecological niches or similar environments.
|
CONVERGENT EVOLUTION
|
X Where they cross is called ....
|
|
Evolution Evidence
Darwin’s views are supported by multiple, independent lines of evidence. Which are? |
Evolutionary patterns of Homology that match patterns in space (Biogeography) and time (the Fossil Record).

|
In a non-evolving population, we can relate the allele and genotype frequencies using the ______.
|
Hardy-Weinberg Theorem
|
H.W. only with assumption of no changes.

GENETIC DRIFT
|
______ is most effective in small populations

Survival of the ______
|
|
the advantage which certain individuals have over others of the same sex and species solely in respect of reproduction
|
SEXUAL SELECTION
|
frequently involves a TRADE-OFF between survival and attracting mates.
|
|
Arises (typically) from competition among males for access to females or mating sites
|
INTRASEXUAL selection
|
Often results in larger body sizes or weaponry that may be advantageous in battle
|
|
Females are usually more selective in mate choice than males
|
INTERSEXUAL SELECTION
|
Mate Choice
|
|
survival and reproduction of any one morph declines if that form becomes too common.
