An embryo is an early stage of development, typically up to 8 weeks after fertilization, when the basic structures of the body are forming. A fetus is a more advanced stage, from 9 weeks until birth, when the organs continue to grow and mature.
The developmental stages of an embryo include the pre-embryonic stage (fertilization to week 2), embryonic stage (weeks 3-8), and fetal stage (week 9 to birth). During the embryonic stage, major organs and structures begin to form, while during the fetal stage, these structures continue to grow and develop in preparation for birth.
During the transition from embryo to fetus stages in human prenatal development, key milestones include the formation of major organs and body systems, the development of limbs and facial features, and the growth of the brain and nervous system. This period is crucial for the overall growth and differentiation of the developing organism.
During the late stages of development, an embryo undergoes rapid growth and further organ formation. At this stage, the major organ systems are well formed, and the embryo is starting to resemble a human fetus. Specialization of tissues and organs continues as the embryo prepares for further growth and development.
Embryos of different species often show similarities in their early developmental stages, such as the presence of a notochord, pharyngeal pouches, and a post-anal tail. These shared characteristics are considered evidence of common ancestry and evolution. Additionally, embryos of various organisms often undergo similar developmental processes, such as gastrulation and neurulation.
An embryo is an organism in its early stages of development before birth or hatching. It is formed shortly after fertilization of an egg by sperm and goes through various stages of growth and differentiation to develop into a fetus in mammals or a young individual in other organisms.

The developmental stages a human undergoes between fertilization and birth include: zygote, blastocyst, embryo, and fetus. During these stages, the fertilized egg undergoes cell division, implantation into the uterus, organ formation, and growth. By the end of the fetal stage, the developing human is ready for birth.
A developmental similarity refers to shared characteristics or processes that occur during growth and maturation in organisms. It can include similarities in physical traits, behavior, or developmental stages between different species or individuals within a species.
Humans exhibit indirect development, as they undergo a series of developmental stages and transformations before reaching their adult form. This process includes distinct stages such as embryo, fetus, infant, child, and adolescent, each with unique characteristics and milestones.

The prenatal stages refer to the developmental stages before birth. They include the germinal stage (conception to 2 weeks), the embryonic stage (2-8 weeks), and the fetal stage (8 weeks to birth). These stages are critical for the growth and formation of all major organs and systems in the developing fetus.
The young or embryo of an animal in the womb, or in the egg; often restricted to the later stages in the development of viviparous and oviparous animals, embryo being applied to the earlier stages.
