Looking at the different dog breeds shown, it could be inferred that each dog is a different species based only on their physical characteristics.
Some are large with long snouts. Some are small with short snouts. Some have long ears that are floppy. Some have short ears that are pointy.
If you didn’t already know that these dog breeds are classified as the same species, what information might be needed to confirm the inference?
similarities in diet
similarities in behavior
similarities in color
similarities in DNA
To confirm the inference that different dog breeds are actually the same species, the most relevant information needed would be similarities in DNA.
Explanation: While physical characteristics can vary widely among dog breeds, DNA analysis can show genetic similarities that prove they belong to the same species. This genetic information is critical in distinguishing species from each other, as it reflects the evolutionary relationships and shared ancestry that may not be evident from physical traits alone.
