The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
Simularities in DNA sequence
True, they descend from a common ancestor.
Simularities in DNA sequence
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
Scientists can study common ancestry through artifacts like fossils, genetic similarities, and anatomical structures in species. Fossils provide evidence of extinct species, genetic similarities show shared ancestry between organisms, and anatomical structures reveal common traits inherited from a common ancestor.
Similarities in DNA sequences, anatomical structures, and developmental pathways provide evidence of a common ancestry among organisms. Additionally, the study of fossils and transitional forms help support the idea of evolution and common ancestry.
Many of their genes are the same.
Fossil record shows a progression of organisms from simple to complex forms over time. Comparative anatomy reveals similarities in bone structure and development between different species, indicating a common evolutionary ancestry. Genetic similarity and shared sequences in DNA among different species provide strong evidence for common ancestry and evolution.
Fossil record: The transition of species over time, as documented through fossils, provides indirect evidence of evolution and common ancestry. Comparative anatomy: Similarities in the anatomical structures of different species, such as the pentadactyl limb in vertebrates, suggest a shared evolutionary history.

Types of evidence for common ancestry among groups include comparative anatomy, embryology, genetics, and the fossil record. These sources provide insights into shared traits, developmental similarities, genetic relationships, and transitional forms, supporting the concept of organisms evolving from a common ancestor.
