Which of these statements best sums up evolution?
rapid change in speciesâ habits and features
rapid development of vestigial structures in a species
change in a population through new species being made
change in a population through genetic variation over time

Change in a population through genetic variation over time best sums up evolution.

Explanation:

Evolution is a process in which the heritable traits are passed on from parent to offspring which lets the organism adapt to the environment.

Darwin claimed that species change over time and give rise to new species and share a common ancestor.

Evolution occurs via Natural Selection as in limited resources the organisms with better features for survival always evolve and pass on the traits to the next generation.

Genetic variation can be because of mutation, random mating between organisms and genetic recombination.

The useful phenotypic traits are formed due to mutations or influx of new alleles by random mating.

The population having received new features which are heritable and better suited for environment will survive and reproduce more viable offspring thus causing change over a period of time.

Change in a population through genetic variation over time

Explanation:

i believe it would be the lungs.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
