Charles Darwin is most known for his theory on what?
Evolution
A group of living organisms with many physical characteristics in common that can interbreed and have fertile offspring.
Species
Name the 2 taxa that are used in Latin Binomial nomenclature.
Genera (or Genus)
&
Species
True or False:
Similarities in the looks of early stage human embryos and various animal embryos suggest that we share a common ancestor.
True
What is the name of the geographical area that the population of a species is found?
Range
True or False:
In Darwin's Inference #3 he states that:
- Evolution over long periods of time leads to Natural Selection
False. Natural selection happens to the individual while evolution happens amongst the population as a result of the more favorable variation becomes more common in each successive population.
Algal bloom as a result of excess nutrients from fertilizer results in the killing off of various aquatic life below the surface of the water. What type of factor would describe this interaction?
Abiotic factor
Which taxa level are organisms LEAST related to each other. (i.e., the most 'zoomed out')?
Domain
There are 2 different theories of evolution (regarding how fast the process is). Name each of them (200 points per correct answer.)
Theory of Gradualism
&
Theory of Punctuated Equilibrium
A random change in DNA (change to sequence of bases) is known as what? (Hint: This is the only process that introduces new characteristics into a population)
A mutation
Darwin's Inference #2 states:
Individuals with more favorable variations are more likely to survive and pass these variations on.
Survival is not random
This is describing the term?
Natural Selection
The relationship in which interacting species of an ecosystems populations remain fairly constant because of one hunting another is known as what?
Predator/prey relationship
The pace of speciation where there are slow and steady changes. In other words, minor changes are occurring with the organism until the final form is much different than the original.
Gradualism
Anatomical features that are similar in shape in different types of organisms. An example of this is the pentadactyl limb.
What is this describing?
Homologous structures
Two Bighorn sheep fighting each other over the favour of attracting a mate is an example of what?
Intraspecific competition
Fill in the blank:
Lamarck contested Charles Darwin's theory of evolution and implied that a(n) _________ ______ is something that an individual can build up over their lifetime, and eventually pass onto their offspring.
Acquired Trait
True or False:
Each generation produces far more offspring than can survive to reproduce.
True
All organisms potentially over-reproduce. (according to Darwin's observation #2)
The category of fossils that are shown in the Phyletic Gradualism models and offers gradual evidence over time of small incremental changes over time.
Transition Fossils
Similar in appearance and function, but do not appear to have the same evolutionary origin.
Ex. Bird’s wing and insect’s wing
What is this describing?
Analogous feature
Newly introduced species that out compete the native species and have no predators to control its population. What is this describing?
Invasive species
The amount of resources available in a given ecosystem that serves as a limiting factor on the population of organisms.
Carrying Capacity
Name the term: geographical separation where species evolve in different places. Eg. Galapagos Islands
Allopatric Speciation
You are making a dichotomous key to distinguish between 8 animals. How many steps should the key have?
7
True or False?:
When an antibiotic attacks bacteria, some of those bacteria will become resistant to that antibiotic and continue to reproduce more of that resistant bacteria in the future.
FALSE
Tail bones in humans are as useful to us as hip bones are to whales. What do you call these types of structures that have been passed on through evolution that the organism has no real use for anymore?
Vestigial Structure
