Macroevolution
Macroevolution is evolution at the level of this or above
What is a species?
Any change in the DNA is this
What is mutation?
The Age of Reptiles and dinosaurs
What is Mesozoic?
The number of dog breeds and cattle provide this type of evidence
What is artificial selection?
These are the co-discoverers of the theory of evolution by means of natural selection.
Who are Darwin and Wallace?
The end of the Permian Period (Paleozoic Era) and the Cretaceous Period (Mesozoic Era) where many species died
What is a mass extinction?
This is random change in small populations due to chance.
What is genetic drift?
The current era.
What is the Cenozoic?
Teeth and skeletons are this type of fossil
What are body fossils?
All of the genes of a population represent its this
What is gene pool?
This is the rapid evolution of many new, diverse species from a single common ancestor often when there are new environmental conditions (i.e. islands)
What is adaptive radiation?
This is due to migrations of populations.
What is gene flow?
The Age of Mammals and Flowering Plants.
What is the Cenozoic Era?
The distribution of living things across the Earth is this.
What is biogeography?
This Law says that the oldest layers are at the bottom and the youngest are at the top.
What is Law of Superposition?
This is the formation of new species where microevolutionary changes accumulate to reproductive isolation leading to new lineages.
What is speciation?
This is a process where organisms with advantageous traits for their environment survive and reproduce more, passing those traits on to their offspring.
What is natural selection?
The Permian extinction and the Age of Invertebrates
What is the Paleozoic Era?
Fossilized footprints, burrows, and coprolites are these type of fossils
What are trace fossils?
Lamarck developed the theory of Inheritance of these which were changes acquired in the lifetime of an organism that will be passed on to their offspring
What is acquired traits?
The diversification of the mammals after the K-T mass extinction and the lemurs of Madagascar are examples of this.
What is adaptive radiation?
This is where individuals choose partners based on specific traits and not in general and an example is hemophilia in the royal families of Europe.
What is non-random mating?
The first mammals
What is the Mesozoic Era?
This is used to determine how closely related two species are
What is a molecular clock?
The first life on Earth appeared during this eon.
What is the Archaean Eon?
