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.

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 ...

Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
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).

Animal breeders say sales of pint-sized farm animals have grown since the COVID-19 pandemic, when more people started raising backyard chickens for fun and fresh eggs. Like chickens, mini farm ...
First pine trees. 140 Ma Orb-weaver spiders appear. 135 Ma Rise of the angiosperms. Some of these flowering plants bear structures that attract insects and other animals to spread pollen; other angiosperms are pollinated by wind or water. This innovation causes a major burst of animal coevolution. First freshwater pelomedusid turtles. Earliest ...
