Carnegie stage 1 to 23 of Human Development
Your exploration of development can begin in many different ways. Follow the guide shown below (Begin, Next, Finally) or use the internal links shown on the left. These main linked pages will give you access to many different embryology resources.
By looking at the Carnegie stages and watching the changes in the embryo's appearance over the first weeks of development. An easy introduction is also given by the week by week timeline of human development or K12 notes for young students.

The Developmental Notes give information about early developmental processes. Later development features can be seen in the System Notes. Each section of notes is organized in a similar way giving: an introduction, overview, developmental abnormalities, stage 13/14 and stage 22 examples of structures, histology and developmental molecular mechanisms.
Developmental Notes - http://embryology.med.unsw.edu.au/devnote.htm (Menstrual Cycle, Week 1 -4, Placenta, Parturition, Postnatal)
Developmental Notes 2 - http://embryology.med.unsw.edu.au/devnote2.htm (Serial Images, Other Embryos, Abnormal Development, Molecular Development, Morphodynamic Development, Statistics, Health)
System Notes - http://embryology.med.unsw.edu.au/sysnote.htm (Heart/Cardiovascular, Respiratory, Coelomic cavity, Gastrointestinal Tract, Head and Neck, Neural, Neural Crest, Eye Ear Nose, Endocrine, Urogenital, Musculoskeletal, Integumentary)
For those wanting to see dynamic processes of development (and have a reasonably quick connection) then the Movies pages are good for watching changes occur.

The study of human development has relied extensively on studying the process in many other animal models (chicken, fly, mouse, zebrafish). For those wanting to see the process of development in other species then the other embryos pages are a good start.

Development does not stop at birth! This new section of notes covers issues relating to postnatal development.

Can jump immediately to lecture and practical Class Notes or alternatively work their way through the

There are many different possible causes and outcomes, look at Abnormal Development.
Abnormal Development - http://embryology.med.unsw.edu.au/Defect/page1.htmThere is also evidence that in utero conditions have a significant impact on future health outcomes, look at Fetal Origins Hypothesis.

Recent changes/updates to the UNSW Embryology website can be found listed on the 2007 Log page.
To put reproduction in a quantitative perspective, there are a number of pages summarizing both Australian, International and World Population trends on Statistics page.

A history of medicine, including embryology, is given by H.S. Williams with additional links to other historical resources including childbirth and Nobel awards on History page.
