How can embryos help scientists understand evolution? Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.

Test Your Understanding 7.Which of the following is true of mammals? (a) they evolved from saurischian dinosaurs (b) they are exotherms (c) they have hair and three middle ear bones (d) mammalian embryos do not have an amnion (e) they all bear their young alive (do not lay eggs).
Using the following terms, explain what classifications and groups humans fall into, from the most general to the most specific: symmetry, germ layers, coelom, embryological development.
What type of evolution do vertebrates have? (Parallel, Convergent, or Divergent)
If you are a scientist studying the evolution of animals, what is the best approach you can use for analysis? analyzing behaviors of living animals with a common ancestry analyzing embryos and skeletons of animals of the same species analyzing DNA sequences and embryonic development analyzing the the fossilized remains of animals from different time periods
How can evolutionary relationships among organisms be determined by comparing embryonic development? A. Embryos of fish and mammals share no similarities B. Embryos retrace their ancestral stages during embryonic development C. Embryos of more closely related organisms show greater similarities in development D. Embryos that develop inside eggs lack similarities to placental mammals
Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity? All vertebrates develop a backbone that protects the spinal cord. All vertebrates live in similar environments which require the same adaptations. All vertebrates inherit the same sequence of DNA from their parents. All vertebrates require the same nutrients during embryological development.
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? a close evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other reptiles a close evolutionary connection between humans and many other reptiles
Using vertebrates as an example, how does comparative embryology prove evolution?
In vertebrate evolution, which of the following evolved most recently? Amniotic egg Jaw Feathers Limbs
Pick a specific animal that exists today and research its ancestor from millions of years ago. How has this animal evolved? Compare it to the ancestor and explain why certain changes may have taken place.
Although other groups of vertebrates are more numerous and have existed longer than mammals, mammals are often called the most advanced form of life. Why?
Many species look similar as embryos. What causes them to appear different as adults? Why does the study of development give insights into evolutionary relationships?
