Question

Transcribed Image Text:C. Evidence from embryology
Embryology is the study of the development of an organism from an embryo to its adult form.
Common structures are shared in the embryo stage and disappear by the time the embryo reaches the
juvenile or adult form. Observe the illustration below of the different stages of embryo from different
organisms and hypothesize which embryo is from each of the organisms. Write the letter in the following
table under the "Embryo category". Then describe how the embryos changed for each of these organisms
from their earliest to latest stages.
