Dolphins and porpoises are both cetaceans and are similar in behavior and overall appearance.
yall are stupid. go to school
A specimen of organisms that are similar in appearance and behavior is called a population. They often share genetic traits, physical characteristics, and behavioral patterns due to their common ancestry and environmental influences.
While there is no one common ancestry, many of them have Irish ancestry.
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
Fossil record: Shows a gradual change in species over time, supporting the idea of common ancestry and evolution. Genetic evidence: Similarities in DNA sequences between different species indicate shared ancestry and evolutionary relationships. Comparative anatomy: Homologous structures among different species suggest a common origin and evolution from a common ancestor.

Common ancestry refers to the shared biological heritage between two or more species, indicating that they all descend from a common ancestor. For example, scientists study common ancestry to understand the evolutionary relationships between different species and trace their evolutionary history.
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
share a common ancestry
Yes.
Some will have common ancestry.
