The universal family tree
This photo is intended to present the concept of 'the family tree'. Perhaps starting in the top right hand corner with Adam and Eve it has now spread into all four corner of the world.
A family tree, or pedigree chart, is a chart representing family relationships in a conventional tree structure. The more detailed family trees used in medicine, genealogy, and social work are known as genograms.
Family trees are often presented with the oldest generations at the top and the newer generations at the bottom. An ancestry chart, which is a tree showing the ancestors of an individual, will more closely resemble a tree in shape, being wider at the top than the bottom.
The longest family tree in the world today is that of the Chinese philosopher and educator Confucius (551–479 BC), and he is the descendant of King Tang (1675–1646 BC). The tree spans more than 80 generations, and includes more than 2 million members. The latest edition is expected to include some 1.3 million living members who are scattered around the world today.
