Which of the following does not provide evi-
dence that living things have been evolving for
millions of years?
(a) fossil record
(b) natural variation within a species
(c) geographical distribution of living things
(d) homologous structures of living organisms
(e) similarities in embryological development

(B) natural variation within a species

Explanation:

Natural variation within a species only shows the differences among organisms within a species and therefore it isn't a piece of evidence that indicates evolution has occurred. Moreover, the geographical distribution of living things, fossil records, homologous structures of living organisms, and similarities in embryological development are all pieces of evidence which corroborate the theory of evolution.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
