Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
It does. It is NOT true that "ontogeny recapitulates phylogeny." But there are numerous facets of embryological development that make no sense except in the light of common ancestry.What we see in developing embryos is a similar pattern of development; one thing developed first, then another thing, then another couple of things, then a bunch of other bits, all in roughly the same order even when compared between different species, we also see features appear that do not exist in the adult form but the embryos have, like limb buds in Dolphins and human tail buds.While it does not prove evolution outright (and the historical method of using it as proof were shown by scientists to be wrong), evolution does explain this well enough that it is not evidence against: These species share a common ancestor, so their developmental processes occur in a similar way, regardless of what other changes have taken place since their divergence.
Scientists use evidence to support or refute hypotheses during their investigations. They gather data through observations, experiments, and measurements, ensuring that their findings are reproducible and objective. This evidence is then analyzed to draw conclusions, which help advance understanding of natural phenomena and inform future research. Ultimately, evidence serves as the foundation for scientific knowledge and theory development.
Puberty is a stage of physical development during adolescence.
The correct answer is GROWTH and/or DEVELOPMENT... one of the characteristics of life... Evolution is the change in a species over a long period of time.... you would not notice these changes in an organism's life. ===================================== When an organism becomes more complex during its own life, that is called growth or growth and development.
The study of similar structures that appear during the development of different organisms is known as evolutionary developmental biology, or "evo-devo" for short. This field seeks to understand how genetic changes can lead to the evolution of new structures and functions during development.

Embryological development in animals displays the same set of nested hierarchies that is known from comparative morphology and genetics, and thus evidence for common descent.Nota bene: this adherence to nested hierarchies is not to be confused with the 19th century hypothesis of ontogeny recapitulating phylogeny. Embryos do not go through evolutionary stages during their development, but they dodisplay atavistic developments that are consistent with phylogenies based on other sources.
Organisms at the embryological level commonly have similar structures called homologous structures, which share a common evolutionary origin. These structures may develop into different organs or parts in adults but have a common ancestral structure during embryonic development. Examples include the pharyngeal pouches in vertebrates and limb buds in tetrapods.

The first organisms evolved during the Archean Eon, which occurred from approximately 4 billion to 2.5 billion years ago. This era was characterized by the development of simple, single-celled organisms like bacteria and archaea.

During embryonic development, all vertebrates go through similar stages such as gastrulation where three germ layers are formed, and neurulation where the nervous system begins to develop. Additionally, all vertebrates exhibit similar embryonic structures such as the notochord and pharyngeal arches. The similarities in embryology across different species provide evidence for common ancestry and evolutionary relationships.
