Which of the following provides the best example of how comparative embryology supports the theory of evolution?
Humans do not lay eggs as birds do, but birds produce yolk sacs instead of embryos, suggesting birds evolved later than humans.

Humans have a tailbone that is visible during embryonic development, which suggests that humans evolved to depend on a useful tailbone.

Humans do not have gills as fish do, but human embryos have gill slits, suggesting humans and fish share a common evolutionary ancestor.

Humans have stem cells that develop in an unpredictable way, whi

When Carolus Linnaeus created his classification system in the 1700s, he sorted organisms based on their physical characteristics. In 1990, Carl Woese and his colleagues introduced a new classification system that sorted organisms into three different domains. Which of the following best explains why this change occurred?

Many of the organisms classified by Linnaeus are extinct, and his classification system was considered outdated.

Linnaeus' classification system did not account for similar organisms being found in different geographic locations.

New genetic research showed that organisms with similar characteristics were not related to each other.

Organisms were discovered that belonged in more than one of Linnaeus' kingdoms, based on physical appearance.
