A team of scientists is investigating evolution in anoles, which are a type of lizard. First, the team obtains a small breeding population of anoles from their natural habitat in a tropical rain forest. Then, they release the population onto a tropical island. The team plans to return to the island in 5 years to observe the population and record any changes. Which mechanism could affect the evolution of the anoles, yet does not involve natural selection? A. competition for food from other lizards on the island B. genetic drift, due to the choice of anoles for the founding population C. decreasing fitness due to hand and feet shape, which may prevent anoles from climbing trees D. increasing fitness due to body coloration, which may provide camouflage from predators

Option-B

Explanation:

Genetic drift refers to the change in the frequency of alleles (determines the trait of an organism) over some time due to chances.

Genetic drift is one of the mechanisms responsible for the evolution of an organism as the alleles could disappear from the small population randomly or new population could be founded.

In the given questions, a small population of anoles were transferred from the tropical rainforest to the new island and when observed after 5 years then the evolution could be observed as a result of the genetic drift. Genetic drift could be responsible as the anoles were chosen from the tropical forest which could be considered a chance or random event.

Thus, Option-B 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]
