When comparing dogs to wolves, scientists found evidence that supports the idea they come from a common ancestor. Which combination of evidence would most strongly support this idea?
comparable anatomies, fossils, and behavior
different anatomies, similar development, and different DNA
comparable anatomies, similar development, and similar DNA
different anatomies, fossils, and behavior

(C) Comparable anatomies, similar development, and similar DNA marks the similarities between dogs and wolves.

Explanation:

Wolves and Dogs share much of the same genetics, so much that wolves can be bred to dogs to produce viable offspring. Because of the genetic similarities, both dogs and wolves share behaviors, physical attributes, social interaction, territorial instincts and forms of communication.

Morphological evidence and genetic evidence both suggest that wolves evolved during the Pliocene and Early Pleistocene eras from the same lineage that also led to the coyote, with fossil specimens indicating that the coyote and the wolf diverged from a common ancestor 1.5 million years ago.

The dog, Canis familiaris, is a direct descendent of the gray wolf, Canis lupus. In other words, dogs as we know them are domesticated wolves.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
