Question

Select the statement(s) that accurately describe how evidence for evolution is demonstrated through the relationship between the ancient Cladoselache (fossil pictured) and modern sharks

The Cladoselache and modern sharks are unrelated and do not share common characteristics.

The skeletons of modern sharks are similar to the fossils found of the Cladoselache.

Modern sharks have a very similar body style to the fossil record of the Cladoselache.

Modern sharks have changed gradually over the course of many years, developing traits that aid its survival.

Modern sharks evolved from a species other than the Cladoselache.

Answer 1

Correct statements: 2, 3, 4, and 5.

Explanation in brief:
- Cladoselache and modern sharks share anatomical features (skeleton structure and overall body plan), so the fossil record shows similarity in skeletons and body style.
- The similarities support gradual change over long time periods with traits that aid survival (evolution by descent with modification).
- Cladoselache is an early relative (not the direct ancestor) of modern sharks, so modern sharks evolved from other ancestral species rather than directly from Cladoselache.
