Which statement about microevolution and macroevolution is true? microevolution can lead to macroevolution. macroevolution can lead to microevolution. genetic drift cannot affect microevolution. natural selection only acts on macroevolution.

Microevolution can lead to macroevolution.

Microevolution refers to the formation of species through the process of speciation. The element responsible for this process is natural selection. In this process changes in the traits occur with time. Macroevolution refers to the development of major group of organisms from groups of species that are distinctly different. For example development of mammals from non-mammalian species or evolution of whales from terrestrial mammals.

Macroevolution refers to the large number of changes that occur in the characteristics of the living organisms, like the evolution of entirely new species from previously existing species. Macroevolution is the result of many  microevolution processes.

Therefore, microevolution can lead to macroevolution is the true statement.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
