A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with, a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis? (1 point) Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees. The cells of the eye in embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different. Amino acid analysis of the cytochrome c protein shows significant differences in the sequence of amino acids between humans and DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla's DNA sequence.

Beyond the Answer

Fossils of humans appearing in deeper sedimentary rock layers compared to fossils of chimpanzees could suggest that humans coexisted with chimpanzees more recently in evolutionary history, challenging the idea that humans and chimpanzees share a more recent common ancestor. If humans are found in older layers, it may indicate they evolved earlier than chimpanzees, weakening the cladogram's interpretation. Moreover, if the eye development patterns in gorillas and humans are strikingly similar while differing from chimpanzees, it could imply a closer evolutionary relationship between humans and gorillas. This evidence would push the cladogram to reconsider the proximity of common ancestors, leading to an intriguing twist in the evolutionary story!
