It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
Structures which are apparently different and performing different functions but their basic structure is similar are called homologous structures and indicate common ancestry eg. fore limbs of bat , whale , horse dog and man apparently different but are made up of humerus , radius , ulna , carpel , metacarpals and phalanges .
Simularities in DNA sequence
That evidence is homologous. Shared common ancestry. In this case you could trace this homology back as far as the common ancestor of gorillas and hominid fossils, or as far back as the emergence of all tetrapods.
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
The three types of homologies are anatomical homology (similar structure), developmental homology (similar embryonic origin), and molecular homology (similar genetic sequence). These homologies provide evidence of common ancestry and evolutionary relationships among different species.
Simularities in DNA sequence
Molecular homologies refer to similarities in DNA or protein sequences between different species that indicate a shared evolutionary ancestry. These homologies provide evidence of common descent and can be identified through sequence alignment and comparison techniques. Studying molecular homologies helps in understanding the evolutionary relationships between different organisms.
Homologies, similarities in structure or genetic sequence among different species, can reveal common ancestry and evolutionary relationships. Studying homologies can help us trace the evolutionary history of organisms and understand how they have diversified over time. By comparing homologous traits, scientists can infer the shared ancestry and evolutionary pathways of organisms.
Developmental homology is recognized in embryos. Two different organisms can have a common embryonic trait, say gill pouches or a tail, but in some of those organisms those gills and tails are lost. Gills pouches and tails are vestigial traits in humans, cats, chickens, etc. These organisms share genetic homologies, but are structurally different.
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
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.
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.
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.
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
Embryonic development can be used as evidence for evolution because it shows similarities in the early stages of development across different species, known as embryonic homologies. These similarities suggest a common ancestry and evolutionary relationships between organisms. By studying how embryos of different species develop, scientists can gain insights into their evolutionary history.
