Like almost everything else in Biology, embryological development follows the pattern of nested hierarchies that we find throughout lifekind.
For instance, in all vertebrates the anus develops first - but not all of those organisms in which the anus develops first are vertebrates: vertebrates are a *subset* of deuterostomes.
This pattern of nested hierarchies persists all through Biology, at all levels: it is found in individual genes and proteins, in morphological features, in behaviour, and in embryological development. And most of the features, whether genetic, behavioural, morphological or developmental, follow closely convergent patterns of nested hierarchies: whether one checks gene A or morphological feature B, one always arrives at a pattern in which apes are a subset of primates, and man is a subset of apes.
In this way, embryological development independently confirms the conclusion drawn from the other forms of these nested hierarchies.
Embryos are used as evidence of evolution because they display striking similarities across different species during early development. These similarities suggest a common ancestry, supporting the theory of evolution. The study of embryonic development provides insights into the evolutionary relationships between species.
Scientists study embryos because they provide insights into how organisms develop and evolve. The features of embryos that support evolution include shared structures across different species, such as gill slits and tails in vertebrates, which suggest common ancestry. Comparing embryos of different species can also reveal similarities in developmental pathways, further supporting evolutionary relationships.
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
The study of fossils and the fossil record can provide evidence of evolution by showing transitions between different species over time. Additionally, comparing the similarities in DNA and genetic material between different species can also provide evidence of common ancestry and evolution. Another study that provides evidence of evolution is observing the changes in populations over generations, such as through experiments with bacteria or studies of natural selection in the wild.

The study of comparative anatomy and embryology can provide evidence of evolution by showing similarities in structures across different species, suggesting a common ancestry. Fossil records and molecular genetics can also provide evidence by tracing the evolution of species over time and showing genetic relatedness between different organisms.
The study of: (i) Cladistics: regional biodiversity, race circles, and geographical isolation; (ii) Genetics: DNA, chromosomes, viral insertions, common mutations; and (iii) Paleontology: fossils. These are some of the types of evidence for evolution.
fossil evidence is when scientist study fossils to figure out how the animal died how it evoled

Because they are evidence of evolution!
Studying embryos can provide insights into the developmental processes that underlie the diversity of life forms seen in evolution. By comparing the similarities and differences in embryonic development across species, scientists can gain a better understanding of evolutionary relationships and how different organisms have evolved over time. This comparative approach helps to identify common ancestry and evolutionary relationships between species.
Paleontology, genetics, molecular Biology, taxonomy, evolutionary development and comparative anatomy, just to name a few.
