Does humans possess vestigial gills and tails during embryological development?

yes it does


What structures do organisms have in common at the embryological level?

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.


Why do you think biologists use both embryological development in their research and studies?

Biologists use embryological development in their research and studies because it provides valuable insights into the processes of growth, differentiation, and patterning that occur during the early stages of an organism's life. Studying embryology helps biologists understand how organisms develop from a single cell into complex, multicellular organisms, and can provide clues about evolutionary relationships between different species.


What is the embryological data definition?

Embryological data refers to information related to the development of an organism from fertilization to birth. This data can include details about cell division, differentiation, and morphogenesis that occur during embryonic development. It is crucial for understanding the processes that shape an individual's growth and formation.


What are problems with embryology supporting evolution?

There are no problems that I am aware of. Embryological development follows, like all characteristics of living organisms, a pattern of nested hierarchies, indicative of common descent. Moreover, many organisms show, during their embryological development, atavistic traits that are not present in the adult form, but would, according to independent morphological and genomic phylogenies, have been present in ancestral forms.


What does the neural tube develop into during embryonic development?

The neural tube develops into the brain and spinal cord during embryonic development.


Do human embryos have tails during development?

Yes, human embryos do have tails during early development, but they typically disappear as the embryo continues to grow and develop.


At what stage of development does a fetus develop its nervous system?

The nervous system of a fetus begins to develop during the first trimester of pregnancy.


Humans possess gills and a tail during certain stages of their embryological development?

it is possible if scientists ever found a way and our body got used to it (ex. your has to get use to a kidney sometimes your body rejects it )

The distinction between protostomers and deuterostomers is based on differences in their what?

Invertebrates develop as either protostomes or deuterostomes. During development, a protostome's first opening is its mouth. Deuterostomes, on the other hand, have their anus as their first opening during development.


All vertebrate embryos develop gills during one of the many growth phases in their development?

It would be more appropriate to say that all vertebrate embryos develop pharyngeal gill slits during one of the many phases in their embryonic development. This is because while gills are specifically present in fishes, pharyngeal gill slits are a general chordate feature.
