Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.

The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.

All these organisms require oxygen to survive.

The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans

Answer 1

. The earliest fossils found in a particular location are the ones that existed the longest ago, so if fish fossils are found in the lowest strata, this suggests that they appeared earlier in evolutionary history. If insects and humans appear in higher, more recent rock layers, this suggests that they evolved later and may be less closely related to fish. Therefore, the evidence that the earliest fish fossils are found in the lowest strata of sedimentary rocks would best support the argument that humans are more evolutionarily related to fish than they are to insects.
