Explanation:

1. For Blank 1: Embryos often have structures that disappear or are modified in the fully - formed animal. So the answer is Embryos.
2. For Blank 2: Scientists study embryos to see if different animals share a common ancestor, by looking for similar structures. So the first part of Blank 2 is common ancestor and the second part is similar.
3. For Blank 3: Pictorial data (like diagrams of embryos at different stages) can be used to compare embryological development patterns across species. So the answer is Pictorial data.
4. For Blank 4: Chickens are an example of an animal that may not look like humans as adults, but their embryos share similarities. So the first part of Blank 4 is Chickens and the second part is adults.

Answer:

Blank 1: Embryos
Blank 2: common ancestor; similar
Blank 3: Pictorial data
Blank 4: Chickens; adults
