Which of the following best describes evolution? a. indivuals compete to survive and only change as a result of competetion b. indivuals with traits best suited osurvival pass these traits to offsprings c. indivuals acquire certian traits during their lifetime and pass these to their offspring d. indivuals change over time as earth's enviorment changes

Answering the question, “Individuals change over time as earth's environment changes” is the statement that best describes evolution. This implies the correct answer is D

Evolution refers to the changes in inheritance characteristics of biological populations across generations.

In other words, it is the phenotypic and genetic changes in the characteristics of biological populations over generations. These changes in characteristics explain the expression genes that are passed from parents to their offspring.

There will be different characteristics in any given population due to genetic recombination and mutation. Evolution takes place when natural selection, which includes sexual selections and genetic drifts, works on this variation, resulting in particular characteristics that are very rare or more common in any given population.

In the mid-19th century, Charles Darwin and Alfred Russell Wallace independently came up with a scientific theory of evolution by selection and Darwin’s book “On the Origin of Species” which was published in 1859, gives the full details of the theory of evolution by selection.

The scientific theory of evolution by natural selection presented three observable facts regarding living organisms.

KEYWORDS:

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
