Fossil Record and Embryology
Questions with Answers
Most people develop wisdom teeth by early adulthood. Wisdom
teeth can cause pain or crowd out their other teeth, so many people
have these teeth removed. Wisdom teeth in modern humans do not
perform a crucial life function.
Which statement best describes the importance of wisdom teeth to
human evolution? - answer They are vestigial structures that once
performed an important function for human ancestors.
Which statement is true? - answer Imprints of leaves or footprints in
sedimentary rock are fossils.
This diagram shows the relative positions of human ancestors in
rock layers.
Which statement about these fossils is supported by the evidence in
the diagram? - answer Homo erectus is the most recent ancestor to
modern humans.
Which of the following pieces of evidence would best support the
argument that humans are more evolutionarily related to fish than
they are to insects? - answer The early stages of embryo
development in fish and humans look strikingly similar while insects
develop very differently compared to both fish and humans.
Human embryos have tails, which become tail bones before birth.
Tails also appear in fish, reptiles, amphibians, birds, and mammals.
Humans also have hair and produce milk to nourish the young,
which is unique to mammals. What does this indicate? - answer a
