Related species have similar embryos.
Fungi develop from spores, which are small reproductive cells that can grow into new fungal organisms under suitable conditions. Embryos are not involved in the reproductive cycle of fungi.
DNA and biochemical analysis involve comparing genetic material and molecular features to determine evolutionary relationships between organisms. Embryology studies the development of embryos to identify similarities and differences in the early stages of life. Morphology examines physical characteristics and structures to group organisms based on shared traits. By combining these approaches, scientists can classify organisms more accurately based on their genetic, developmental, and physical characteristics.
Embryos develop externally through a process called embryogenesis. This involves the growth and differentiation of cells into specialized tissues and organs. The embryo receives nutrients and support from the environment through structures like egg membranes or placenta, depending on the species.
Embryos of different animals may look similar due to shared evolutionary history. This concept is known as embryonic homology and suggests that animals with a common ancestor will display similarities during early development. Shared genetic and developmental pathways contribute to these similarities, even if the adult forms of the animals look very different.
Similar structures in embryos refer to the presence of common anatomical features and developmental patterns observed in the early stages of different organisms. This similarity is often used as evidence to support the theory of common ancestry, suggesting that these organisms share a common evolutionary history. Studying these similarities can provide insights into the relationships between different species and the processes of evolution.

homologous structures. These structures indicate common ancestry and are evidence for evolution. Examples include the wing of a bird and the flipper of a dolphin.
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.
Comparing embryos of different organisms can reveal similarities in their development, suggesting a common ancestry. These similarities in early development provide evidence for evolution by showing that different species share a common evolutionary history. Studying embryonic development can help trace the evolutionary relationships between different species and support the idea of descent with modification.
Actually yes it can. Embryos, DNA sequences, and fossils amongst others things can help show similarities within species. This can show that those species have similar traits because they evolved from a common ancestor. But those differences show why they are different species and thus evolving.

The process of looking at embryos at different stages of development is known as embryology. Embryology involves studying the growth and differentiation of embryos from fertilization to the fetus stage. It helps scientists and researchers understand the biological processes that lead to the formation of complex organisms.
No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.

Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. All of the animals except for fish, lose their gills slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage
Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
