The ability to survive and reproduce in an environment.
What is fitness?
A group of organisms that can breed naturally in nature and have fertile offspring.
What is a species?
True or False - Evolution occurs within individual organisms.
False
The preserved remains or traces of an organism from the past.
What are fossils?
This occurs when organisms are separated by a river, valley, mountain, etc.
What is geographical isolation?
what are cladograms used for
to show a relationship between animal groups.
The scientist who discovered evolution, writing On the Origin of Species
Who is Charles Darwin?
An inherited trait that enhances an organisms ability to survive. (Favorable variation)
What is an adaptation?
"American murderlog" is an example of this term for identifying an organism
What is a common name.
Changes in the genetics of a population due random chance such as organisms being killed by a forest fire.
Genetic drift
The study of similarities in the early development of embryos.
What is embryology?
This occurs when flowers pollinate in different seasons.
What is temporal isolation?
A trait held by all subsequent organisms on a cladogram
A shared Derived Characteristic
DOUBLE JEOPARDY
When an organism completely dies out.
Extinction
A version of a gene.
What is an allele?
The Latin, two-part name unique to every organism
The type of natural selection that favors only the extreme in a range of traits, such as fur color matching the environment.
Directional selection.
Structures that no longer have a function.
What is a vestigial structure?
Reproductive isolation occurring PRIOR to fertilization.
Prezygotic isolation
Another thing cladograms are used for is finding ...
common ancestor
How does the following diagram display an evolutionary relationship between organisms.
The embryologic development is very similar early on.
DOUBLE JEOPARDY
A change in the genetic material which can cause variation in a population.
What is a mutation?
DOUBLE JEOPARDY
A diagram that shows the traits and evolutionary relationship between groups of organisms.
What is a cladogram?
What do the p's and q's in the Hardy-Weinberg equation represent (identify both)?
p - the % of the dominant allele
q - the % of the recessive allele
Analogous structures
When organisms can no longer mate (producing a new species) this process occurs.
What is speciation?
How closely related are crocodiles and birds? What is the last trait they have in common?
Very - Eggs with Shells
Name the 5 conditions required to meet the Hardy-Weinberg principle.
1. No genetic drift
2. No gene flow
3. No mutation
4. Mating must be random
5. No natural selection
The process where some members of a population would be better equipped for survival in the environment and therefore survive to reproduce.
What is natural selection?
What are the 8 levels of classification, in order?
Domain -> Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> Species
Name the 5 conditions required to meet the Hardy-Weinberg principle.
1. No genetic drift
2. No gene flow
3. No mutation
4. Mating must be random
5. No natural selection
Name three types of molecular evidence that can be used to show relatedness (common ancestry).
What is comparing DNA, Proteins, Genes, RNA, Amino Acids.
DOUBLE JEOPARDY
in order for two similar groups of organisms to form into different species, this must occur.
What is reproductive isolation?
Which pair is more closely related - Sharks and Ray-Finned Fishes or Primates and Rodents? Why?
Primates and Rodents -- they have more shared traits and are on a split branch.
Structures that have different mature forms but develop from the same embryonic tissues.
What are homologous structures?
Give at least 3 pieces of biological evidence based on homologous structures that Birds, Amphibians, and Mammals are related.
Will Vary --
4 limbs, similar organ systems, etc... Whatever makes sense.
