A population of lizards lives in a marsh near the ocean. Members of this population have striped tails that can be yellow, orange, or red. Most members of the population have yellow striped tails. During a storm, four lizards get swept into the ocean on driftwood and end up on an island several miles away. All four of the lizards have orange striped tails. These lizards start a new population on the island, and all members of the new population have orange striped tails. In the example above, the new lizard population had less genetic variation than the original population because of .

The question is incomplete as it does not have the options which are:

A. Speciation

B. the founder effect

C. natural selection

D. gene flow

Founder effect

Explanation:

The founder effect is the phenomenon observed when the members of the population establish a new population.

This effect is observed due to the immigration and emigration of the individuals of the population.

In the given question, the four lizards swept away with the ocean and reached a new island. There they reproduced and flourished and by the time they formed the new population with orange stripes. This is the case of the genetic drift especially the founder effect in which the new alleles for the orange tail expressed.

Thus, the founder effect is the correct answer.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
