Human development is the process of growing to maturity. In biological terms, this entails growth from a one-celled zygote to an adult human being.
Fertilization occurs when the sperm successfully enters the ovum's membrane. The genetical material of the sperm and egg that combine to form a single cell, called a zygote, and the germinal stage of prenatal development commences. The germinal stage refers to the time from fertilization, through the development of the early embryo, up until implantation. The germinal stage is over at about 10 days of gestation.
The zygote contains a full complement of genetic material and develops into the embryo. Briefly, embryonic developments have four stages: the morula stage, the bastula stage, the gastrula stage, and the neurula stage. Prior to implantation, the embryo remains in a protein shell, the zona pellucida, and undergoes a series of cell divisions, called mitosis. A week after fertilization the embryo still has not grown in size, but hatches from the zona pellucida and adheres to the lining of the mother's uterus. This induces a decidual reaction, wherein the uterine cells proliferate and surround the embryo thus causing it to become embedded within the uterine tissue. The embryo, meanwhile, proliferates and develops both into embryonic and extra-embryonic tissue, the latter forming the fetal membranes and the placenta. In humans, the embryo is referred to as a fetus in the later stages of prenatal development. The transition from embryo to fetus is arbitrarily defined as occurring 8 weeks after fertilization. In comparison to the embryo, the fetus has more recognizable external features and a set of progressively developing internal organs. A nearly identical process occurs in other species.

People typically select a specific period of time (child, teen, aging) or choose to study one topic from prenatal to death. More at http://www.DevelopmentalDave.com.

http://www.einstein.yu.edu - When do babies start talking? In this video, you will see and hear developmental milestones in speech during a child’s first year—from the very first sounds to first words. Babies start communicating much earlier than you may think. Einstein speech-language pathologist Nancy Tarshis shows parents what to expect, how to encourage communication, and what to do if they are concerned that their child has a developmental delay. She also goes though the stages of baby talk for those who want in-depth information. Yes, there really is a “goo stage.” Recommended for parents and for child development professionals. Ms. Tarshis is supervisor of speech and language services at the Children’s Evaluation and Rehabilitation Center (CERC) at Albert Einstein College of Medicin...

Delayed development of speech and/or language is one of the most common reasons for parents of preschool children to seek the advice of their family doctor. Although some children rapidly improve, others have more persistent language difficulties. These long-term deficits can adversely affect academic progress, social relationships and mental well-being.although Dlds are common, we are still a long way from understanding what causes them and how best to intervene.

The book demonstrates that private property protected by law, the principle of 'getting-the-prices-right', and the emergence of effectively functioning markets are the outcome of a given society's historical development and institutional fabric. Peter Ho argues that the successful creation of new institutions hinges in part on choice and timing in relation to the particular constellation of societal, economic, political and cultural parameters.

Organisms can differ drastically in how the embryo develops, especially when they belong to different phyla. For example, embryonal development in placental mammals starts with cleavage of the zygote into eight uncommited cells, which then form a ball (morula). The outer cells become the trophectoderm or trophoblast, which will form in combination with maternal uterine endometrial tissue the placenta, needed for fetal nurturing via maternal blood, while inner cells become the inner cell mass that will ...
