Forces of Evolution
When the valiant prairie dog calls out to warn his family of impending danger, potentially making himself more vulnerable prey.
What is Kin Selection?
An accurate way to compare a species to a common ancestor, or to compare one species to another, using biomolecules.
What is DNA testing?
The most specific taxon in grouping of living things.
What is species?
Name one of Mr. Burkhead's favorite colors today. (they can change from day to day)
Teal, Purple, Orange
An example of Sexual Selection that has nothing to do with birds
(many examples)
Any animals whose males compete for access to females.
Any animals whose females choose a mate based on a specific trait or action that shows their health and fitness.
A method of determining if a species was alive before or after another species based on its place in the layers of the Earth
Relative Dating - This will not necessarily tell you the exact age of a fossil, only what came before or after it on a timeline
The hierarchical grouping of living things based on shared characteristics.
What is classification?
Different versions a particular gene
What is an allele?
Low gene flow between populations can lead to this.
What is speciation?
Studying Embryology can tell us this about evolution.
What is that many organisms have very similar embryos at an early stage of development, so they likely share a common ancestor.
Also, that the processes that control early development have not changed or evolved since that common ancestor.
Change in a population over time
What is definition of Evolution? Could be change in allele frequency in a population. Change in genetics, traits (phenotypes), characteristics, etc.
If 2 organisms can't successfully breed, they are not part of similar groupings called this
What are species? 2 species can't successfully breed and have fertile offspring
A natural disaster kills random members of a population of squirrels. Most squirrels that died were your standard gray squirrel, leaving mostly red squirrels in the population. The next 3 generations in this population show an increasing frequency of red squirrels demonstrating this evolutionary force
What is genetic drift?
The difference between homologous structures and analogous structures.
What is homologous structures are similar and come from a common ancestor, while analogous structures are similar but are not inherited from an ancestor.
H.S. - penguin wings and ostrich wings
A.S. - Oriole wings and bumblebee wings
Two characteristics that began to differentiate early human ancestors from other primates
What are bipedal movement and larger brains?
The winners of the Women's NCAA basketball tournament?.
Who are UCLA?!
The reason some bird populations on tropical islands evolve elaborate plumage and mating rituals
There is enough resources to support large populations and a lack of predators, so evolution is driven by sexual selection instead of natural selection
The way that Endosymbiosis supports Evolution
The theory of Endosymbiosis discusses the evolution of single celled prokaryotes to eukaryotic cells
The reason bacteria and viruses evolve very quickly compared to other organisms.
What is their very high rates of reproduction, and therefor high rate of mutation during replication.
Name 3 characters from the Lord of the Rings besides Frodo.
Soooooo many
