In the early stages of development embryos dogs pigs and humans resemble one another this observation suggests that these animals may have?

The observation that early embryos of dogs, pigs, and humans resemble one another strongly suggests that these animals share a common ancestor.

Here's why:

* Evolutionary Relationships: Evolutionary theory posits that all life on Earth is connected through a common ancestor. Species that are more closely related share a more recent common ancestor.

* Developmental Similarities: The similar early development patterns indicate that these animals inherited a shared set of developmental genes from their common ancestor.

* Homology: These similar developmental features are examples of homology, meaning they share a common origin even if they have slightly different functions in different species.

This shared developmental pattern is a powerful piece of evidence supporting the idea that all living organisms are interconnected through evolutionary history.
