One of the earliest experimental embryology experiments was conducted by Wilhelm Roux, who used a hot needle to kill one of the cells in an amphibian embryo at the two-cell stage. In the experiment, the remaining living cell formed only half of an embryo. However, later vertebrate experiments showed that by completely separating cells in early embryos, each can make complete individuals. What could explain the discrepancy in these experiments?

Insects have three thoracic (trunk) segments. While researchershave found insect fossils with pairs of wings on all threesegments, modern insects have wings or related structureson only the second and third segment. It turns out thatin modern insects, Hox gene products act to inhibit wingformation on the first segment. The treehopper insect (above)is somewhat of an exception. In addition to having wingson its second segment, the treehopper’s first segment has anornate helmet that resembles a set of thorns, which a recentstudy has found to be a modified, fused pair of “wings.” Thethorn-like structure helps to camouflage the treehopper intree branches, thus reducing its risk of predation. Explain howchanges in gene regulation could have led to the evolution ofsuch a structure.
People could observe the development of an embryo before they had the tools to see cells and parts of cells such as DNA. How they explained the development from embryo to organism and how would the discovery of DNA and how DNA "works" have changed how scientists could research development?
Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution? A. The similarities suggest that chickens and humans are the direct descendants of modern day fish with tails and gill slits. B. The similarities suggest that vertebrates passthrough each of the adult stages of their evoluntionary history as they develop. C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slits
