Definitions
Extinction
Who said this - Darwin, Lamarck, or both?
-Certain traits help organisms survive and reproduce better than other organisms without those traits.
Darwin
Which component of evolution is being described: Natural Selection, Variation, or Fitness? You take your pet German Shepherd to a dog park and see many different breeds of dogs. They are all the same species, Canis lupus familiaris, but have different body shapes, colors, and face shapes.
Variation
Chemicals produced by microbes that either kill (bactericidal) or inhibit the growth (bacteriostatic) of bacteria are _______
Antibiotics
Another term for a cladogram is a _____
Phylogenetic tree
Artificial Selection
Who said this - Darwin, Lamarck, or both?
-Organisms have changed over time and are still changing.
Both
Sometimes animals have traits that don’t seem to make sense, like the long tail feathers of a peacock. What type of evolutionary selection explains this?
Sexual Selection
What is the evolutionary process by which two related populations become NEW distinct species.
Speciation
Give two examples of how a species could go extinct. (Multiple answers are correct)
Habitat degradation, predation, disease, natural disaster
Populations don't breed because they reproduce at different times (season, day)
Temporal Isolation
Who proposed the theory of Acquired Characteristics - Darwin or Lamarck?
Lamarck
When a single species evolves into several different forms in response to different selection pressures, it is called ________ (two words)
Adaptive Radiation
What is the word to describe the evolution of two or more species that depend on each other and evolved adaptations to each other’s influence?
Coevolution
How is a scientific name written?
Genus species
The presence of functionless and reduced remnants of organs that were once present in their ancestors
Vestigial Structures
Who proposed the theory of Evolution by Natural Selection?
Darwin
Fill in the blank: Wings of bats and birds, fins of fish and dolphins perform the same function, but these species are not closely related. These are an example of: ______
Analogous Structures
What occurs when different adaptations evolve in closely related organisms as they compete or move to new locations?
Divergent Evolution
It is changing from fall to winter in the Arctic are dropping rapidly and the polar bears must be warm or they will freeze to death. Over time, the allele for a (thick/medium/thin) coat increase.
Thick coat
Populations don’t breed because physical separation of members of a population (canyon, islands, isolated ponds, mountains, etc.)
Geographic Isolation
Who said this - Darwin, Lamarck, or both?: Organisms could decide to change something about their body and pass on that change to their offspring.
Lamarck
The three domains of living things are:
Eukarya, Archaea, Eubacteria
What vocabulary best matches this definition? Intermediate fossil forms show that organisms have evolved over time from ancient ancestors
Transitional Species
Which component of Evolution is being described: Competition, Adaptation, or Variation? You visit a local reservoir where you feed ducks and other birds. Every time you feed them, you notice that they fight for the best pieces, and some birds do not get any pieces of food. All living things struggle to get the necessary amount of food, water, and shelter.
Competition
