Unborn or unhatched offspring are called embryos. The study of these embryos is known as embryology. By studying the development of different types of organisms, scientists can compare and contrast their growth at different stages of development.
The diagram shows the different stages of embryo development in five organisms.
The diagram shows five stages of embryo development in five different organisms: fish, tortoise, chicken, rabbit, and human. The first stage shows the eggs of all the organisms. The second stage shows all the embryos developing a head and a curved tail. The third stage shows all the embryos beginning to develop limbs and curling up, except for the fish, which becomes long and straight. The fourth stage shows all embryos developing facial features and starting to differ from each other in appearance. The fifth stage shows what the embryos will look like once they are born or hatched.
Multiple Choice Question
Which pattern can be seen in the diagram?
A.
Each embryo goes through very different stages of development.
B.
Mammals look very similar to each other during limb development.
C.
Birds and reptiles have very different appearances throughout development.
D.

1 answer
The correct answer is A. Each embryo goes through very different stages of development.
This option reflects the observation that while there are similarities in early stages of development across different species, the subsequent stages show distinct differences in how each organism develops, especially as they approach their final forms.
