100
This is the out-dated the idea that living material arose from non-living material.
What is spontaneous generation?
100
How do we define organisms as belonging to the same species?
If they can interbreed and produce live, fertile offspring.
100
Scientific names are in this language.
What is Latin?
100
This type of speciation occurs when new species evolve without the requirement of geographic isolation.
What is sympatric speciation?
100
This is the evolutionary history of an organism or group of organisms.
What is phylogeny?
200
What do scientists presently believe were the first types of living things?
What are prokaryotes?
200
What type of speciation involves a geographic isolator that prevents former members of a population from interbreeding?
What is allopatric speciation?
200
This scientist designed a classification system based on physical and structural similarities.
Who is Linneaus?
200
This idea suggests that evolutionary processes occur slowly over millions of years.
What is gradualism?
200
This is a pattern of evolution in which species that were once similar to an ancestral species become increasingly different.
What is divergent evolution?
300
This autotrophic process allowed early life forms to obtain energy from breakdown of inorganic compounds such as sulfur and nitrogen.
What is chemosynthesis?
300
Give an example of a pre-zygotic barrier to reproduction or interbreeding?
What are genetic isolation, behavioral isolation, temporal isolation, or structural isolation?
300
This is the branch of biology that groups and names organisms based on studies of their different characteristics.
What is taxonomy?
300
This idea suggests that evolutionary processes occur in rapid bursts with long periods of genetic equilibrium in between.
What is punctuated equilibrium?
300
The evolution of what process allowed for the production of the ozone layer and a new environmental condition to be exploited?
What is photosynthesis?
400
One theory for how eukaryotes may have evolved is supported by evidence which includes the fact that these two organelles have DNA of their own.
What are mitochondria and chloroplasts?
400
Hybrid inviability and hybrid infertility are examples of what type of barrier to interbreeding?
What is post-zygotic?
400
This is the two-word naming system developed by Carl.
What is binomial nomenclature?
400
What type of event might allow for a high rate of speciation?
What is major environmental change?
400
In systematics, what do we call a group in which all the members are more closely related to each other than to any individuals outside the group?
What is a monophyletic group?
500
What theory suggested by Lynn Margulis explains how eukaryotes may have evolved as a result of mutualistic relationships between early prokaryotes?
What is endosymbiont theory?
500
Asexual species can be characterized using this concept.
What is a morphological species concept?
500
This is a modern approach to classification that attempts to reconstruct the evolutionary history of organisms.
What is systematics?
500
This is a type of divergent evolution in which an ancestral species evolves into an array of species to fit a number of diverse habitats.
What is adaptive radiation?
500
These are the three domains of living things on this planet.
What are Eukarya, Eubacteria, and Archaeabacteria?
