How do studies of body structure and embryos support the idea of common ancestry

Studies of body structure and embryos support the idea of common ancestry:

The theory of common descent expresses that every living life form is relatives of a solitary predecessor. Life systems manage the investigation of the body structure of living beings including people. The hypothesis of advancement clarifies that few out of every odd component of a predecessor's undeveloped organism has appeared in its relatives.

That clarifies why undeveloped organisms form into various species after some time. The investigation of undeveloped organisms likewise gives data on development.

For instance, human undeveloped organisms have a tail-like structure at a specific phase of advancement and gills at one of the stages. Instances of proof from embryology which underpins basic parentage incorporate the tail and gill cuts present in all early vertebrate undeveloped organisms.
