He sailed on the HMS Beagle around the world and published the Origin of Species
Who is Charles Darwin?
Only land plants
What are plants?
Common ancestor of all organisms in the tree
Bacteria, Archaea, and Eukarya
What are the 3 domains of life?
Methods of defining what makes a group of organisms a species
What is the species concept
All the alleles in a population
What is a gene pool?
Glaucophytes are unicellular and were the earliest clade to diverge from this group
What are algae?
Two species, each other's closest relatives
Divide by binary fission, unicellular and no membrane-enclosed cytoplasmic organelles
What is a prokaryotic organism?
Groups of organisms based on physical traits
What is morphological species concept
p+ q = 1 and p2 + 2pq + q2 = 1 are formulas used in this method to measure evolution
What is Hardy-Weinberg equilibrium?
Liverworts, mosses and hornworts are examples of this phylum
What are nonvascular land plants?
Traits that differ from the clade's ancestor (evolved later). For example, jaws or 4 limbs
What is a derived trait?
Retain violet dye, uniformely dense cell wall and contains 5 times the amount of peptidoglycan
Speciation in the same place with no physical barrier
What is sympatric speciation
What is natural selection?
Fungal commensalist that live within aboveground plant parts without harming the plant
What are endophytic fungi?
Containing only some descendants of a particular ancestor
What is paraphyletic?
A group or organisms that are able to interbreed
What is a species?
A drought on an island prevents Finches from eating their normal seeds. They are forced to eat larger seeds in order to survive resulting in their beak size increasing - an extreme.
What is directional selection?
Transports sugars from the leaves to the plant
What is phloem?
Traits not likely to evolve over and over in separate lineages thus the simplest way is most likely
What is parsimony principle?
This virus causes smallpox and herpes with many being bacteriophages
A fossil that looks like an antelope with short leg bones and a living descendant antelope
What is phylogenetic species concept?
