Mechanisms of Natural Selection
The result of only planting one species of plants / crops?
What is decrease in genetic variation / genetic diversity.
The macromolecule that is made up of a 1:2:1 ratio of Carbon, Hydrogen, Oxygen, Hydrogen.
What is Carbohydrate?
The change in frequency of an existing gene variant in the population due to random chance or natural selection.
What is genetic drift?
The result of DNA mutations randomly leading to new traits leading to a new species from the original population increasing success.
What is speciation?
The conclusion of Miller and Urey's classic experiment.
What is the formation of biological molecules formed from simple molecules found on Earth?
In natural selection the competition between organisms within a population for limited resources and predator / prey relationships.
What is the struggle to survive?
Which macromolecule is composed of a sugar, nitrogen base, and a phosphate group.
What is Nucleic Acid?
A population of organisms changing over time in response to parasites, environmental pressures like the development of resistance to pesticides or antibiotics amongst insects or bacteria respectively.
What are observable changes?
a form of a hereditary characteristic is call a
What is trait
What is an explanation that life could have originated from a prokaryotic cell?
The reason there is an increase in frequency of desirable traits like speed or camouflaged color.
What is the reason faster or best camouflaged organisms have better chance of surviving with the frequency of these genes?
This macromolecule acts as a catalyst speeding up chemical reactions.
What is protein?
What evolutionary process is observed when there is a transfer of genes between distinct populations of organisms within the same species. Due to immigration, they are now in same place interbreeding and sharing genes.
What is gene flow?
Process whereby an organism becomes better able to live in its habitat or habitats
What is adaptation?
The conclusion of Louis Pasteur and Francisco Redi experiments of the origin of life.

What is that living things come from living things?
The reason that a species with wider range of genetic traits within a population are able adapt to changing environments.
What is increased genetic diversity?
The macromolecule that is made up of Carbon, Hydrogen and Oxygen but is not a perfect ratio of 1:2:1
What is Lipid?
The explanation that depicts the embryonic development of different species sharing similar developmental stages.
What is embryology?
if two organisms have similar traits and DNA they probably share a common
What is ancestor
The result of having larger skull size and increased brain size.
What resulted in increase tool use, language development & communication?
A result of what can happen to organisms / species who lack genetic variation prohibiting them to adapt to new environments.
What is become extinct?
The macromolecule with a monomer unit of amino acid.
What is protein
Geographical distribution of organisms, which shows how species are related to each other based on their location and the historical movement of continents
What is biogeographical evidence ?
Any of a family of erect bipedal primate mammals that includes recent humans together with extinct ancestors.
What is hominid?
A common observable trend in from fossil record between H. Sapiens and early hominids.
What is decrease jaw size?
