TimeTree is a free public database developed by S. Blair Hedges and Sudhir Kumar, now at Temple University, for presenting times of divergence in the tree of life. [1] [2] The basic concept has been to produce and present a community consensus of the timetree of life [3] [4] from published studies, and allow easy access to that information on the web or mobile device.

The example also shows how the chart's overall style can be overridden by more specific styles set by {}. In this case, the color of the first row of cells is set to yellow using the features of the {{ Tree chart }} template; see that template's documentation for details on how to specify the CSS of rows and individual cells of a chart.
Time-lapse of a flower opening Plumeria trees flower from early summer to fall. Their blossoms grow in clusters on ends of the stems, they are made of tubular corolla with a length of 2–4 inches (5.1–10.2 cm) that split sharply into five rounded and waxy petals that overlap each other.
Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
Life on Location: Time Warp goes behind the scenes of a time-lapse sequence in an English woodland. Because actually growing plants outdoors would prove a challenge to film (with constantly changing conditions) this scene used plants grown in a studio on a bluescreen duplicating a real outdoor backdrop. The entire process took two years to make.
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from the wood of old trees.
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
