Evidence
The whole remains of these help scientist identify when organisms lived.
What is a Fossil
He wrote the Origin of Species
Who is Charles Darwin
These are mostly harmful. However, in some bacteria and insects, can have benefits in developing resistance.
What is Mutations
This principle states that If the allele frequencies do not change, the population will not evolve.
What is the Hardy-Weinberg Equilibrium
This is when we see the first sign of life.
What is Proterozoic
The similar features in these very small and different organisms suggests evolution from a distant common ancestor.
What is Embryos
He spent 5 years on a boat in the 1800s and was able to write a book of his observations that scientists still use today.
Who is Charles Darwin
This is often called sexual selection and means that the females will choose who they mate with.
Even though there are different species, they all seem to evolve similar characteristics, but still are different species.
What is Convergent Evolution
After Eons
What are Eras
In this field of study scientist discovered that the different environmental conditions favored different traits.
What is Biogeography
He said that a giraffe need only to stretch its neck to have ling neck babies.
Who is Jean-Baptiste Lamarck
Due to a natural disaster, this can cause a loss of genetic diversity
What is Genetic Drift
This is the number of times an allele appears in a gene pool. When it changes, we know evolution is underway.
What is Frequency (allele frequency)
After the ice age, the mammals began to take over the planet in this era
What is the Cenozoic
This study suggests Fossil evidence supports the idea that whales descended from hoofed animals.
What is Paleontology
The main contributor to Taxonomy
Who is Carl Linnaeus
This always has a positive effect, because it favors the transmission of favorable traits.
What is Natural Selection
This process of evolution can happen gradually or instantly.
What is Extinction
This is our time!!
What is Quaternary
Sometimes called comparative anatomy this study states that some organisms have body parts that are similar in structure but might be used differently.
What is Morphology
She proposed in the 1960s that the organelles of eukaryotic cells were once prokaryotic cells that have been engulfed by a larger prokaryotic cell
Who is Lynn Margulis
During this type of gene flow, there is an introduction of alleles to a population.
What is Immigration
Due to isolation species will evolve into distant species.
What is Speciation.
This period is when the Earth was most rich with plants and oxygen.
What is Cretaceous
