Macroevolution
Macroevolution is the changing of species over time at the organism level. Subtopics include phylogeny, speciation, cladistics, and taxonomy.
Macroevolution
A brief definition of the term "macroevolution".
Patterns of Macroevolution
A look at the patterns macroevolution can follow in order to create new species.
Vestigial Structures
Vestigial Structures in humans show ways the Homo sapiens species has evolved over time.
Phylogenetics
An introduction to phylogenetics and how scientists use it to piece together the history of life on Earth.
Speciation
Defining what is a species and the processes that explain how they change over time.
Types of Speciation
A brief description of the four types of speciation: allopatric, sympatric, peripatric, and parapatric.
Can Microevolution Lead to Macroevolution?
A quick look at whether or not microevolution and macroevolution are related.
Evolutionary Clocks
A brief definition of a evolutionary clocks and how they are used to determine evolutionary relationships.
Gradualism vs. Punctuated Equilibrium
A look at the differences between possible rates of evolution gradualism and punctuated equilibrium.
Taxonomy
Organisms are grouped into categories of evolutionary similarities by a system called taxonomy.
Cladistics
A definition of the term "cladistics".
Phylogeny
A definition of the word "phylogeny".
