Embryogenesis, the first eight weeks of development after fertilization, is an incredibly complicated process. It's amazing that in eight weeks we're transforming

Embryonic development of plants and animals vary. Even in animals, every species undergoes different stages during embryonic development.

Embryological Development. All human beings begin life as a fertilized egg, called a zygote, which is a single cell about one-fifth the size of the period at the end of this sentence. By adulthood, the human body has grown to more than a hundred trillion cells, most of which are highly specialized for particular tasks.

Most animal species undergo a separation of tissues into germ layers during embryonic development. Recall that these germ layers are formed during gastrulation, and that each germ layer typically gives rise to specific types of embryonic tissues and organs. Animals develop either two or three embryonic germ layers (Figure 1).

Let's see these processes at work in some early developmental milestones. Figure 1: Fertilzation.

2009 Aug;27(2):E2. doi: 10.3171/2009.5.FOCUS0997. With a monkey embryo viable to 20 days, he could start introducing human cells into that embryo and explore the first flurry of genetic, molecular and chemical changes that dictated early development. The early development of the eye is arrested or impaired, as early as the gastrula phase (within 2 weeks of fertilization). Alcohol impairs neural crest cell migration - and so the clinical manifestations of fetal alcohol syndrome may mimic other neurocristopathies.
