Paleozoic, Mesozoic, or Cenozoic
The current era
What is the Cenozoic Era?
Any change in the DNA is this.
What is a mutation?
Macroevolution is evolution at this level or higher.
What is species?
Bones and teeth are this type of fossil,
What are body fossils?
these are the co-discoverers of the theory of evolution by means of natural selection.
Who are Charles Darwin and Alfred Russell Wallace?
The Age of Dinosaurs and Reptiles was the.
What is the Mesozoic Era?
This occurs in small populations at random and due to chance.
What is genetic drift?
The end of the Permian Period (Paleozoic Era) and the end of the Cretaceous Period (Mesozoic) mark two of these.
What is mass extinction?
An example of direct observation is.
What are bacteria and/or the Galapagos (Darwin's) finches?
All of the genes of a population is this.
What is a gene pool?
The Age of mammals and flowering plants.
What is the Cenozoic Era?
This is the movement of genes as a population migrates.
What is gene flow?
The rapid evolution of many new, diverse species from a single common ancestor often when there are new environmental conditions (i.e. islands) is this.
What is adaptive radiation?
Fossilized footprints, coprolites, and burrows are these types of fossils.
What are trace fossils?
Microevolution occurs at the level of this.
What is the population?
The Age of Invertebrates and the Permian mass extinction were part of the.
What is the Paleozoic Era?
Variation, inheritance, and adaptation are part of.
What is natural selection?
Speciation is the formation of new species due to this.
What is reproductive isolation?
This examines and compares the physical traits and structures of organisms to establish their evolutionary relationships and includes homologous structures and vestigial structures.
What is comparative anatomy?
The first life on Earth occurred during this Eon.
What is the Archaean Eon?
The break up of Pangaea and the K-T mass extinction (Cretaceous - Tertiary) occurred during this era.
What is the Mesozoic Era?
An example of this, where individuals choose partners based on specific traits, is hemophilia in the royal families of Europe.
What is non-random mating?
The diversification of mammals after the K-T extinction and many species of lemurs in Madagascar provide examples of this.
What is adaptive radiation?
This is used to determine how closely related two species are
What is a molecular clock?
Lamarck developed this theory on evolution that stated that features acquired during the lifetime of an individual could be passed on to their offspring.
What is Inheritance of acquired Traits?
