During prenatal development, there are three different stages that an embryo/baby human being goes through, including: This happens during the first 2 weeks after conception and ends when the zygote becomes implanted to the uterine wall -- (over half do not successfully implant) This happens from two weeks after conception to 8 weeks of human organism development. This stage begins when the zygote is implanted in the uterine. During this time placenta and major organs develop, along with red blood cells and the heart. This stage takes place after the first 8 weeks after conception until the human baby is birthed; approximately the final 3 months. Throughout the final stage there is a rapid growth of the brain and body completing the baby"s development. During the three stages of prenatal development nature and nurture matters in utero. Critical periods (nurture): development stages when environmental influences have the most impact. Thalidomide (chemical in certain medicine), poor nutrition, stressing.
