Visualize taxonomy easily with Darwin. Don't worry about phyla, subclasses, infraorders, and so on - we take care of that for you.
Use Darwin to build a phylogenetic tree of different taxa, as relationships and missing links are created automatically.
A "taxon" (or "taxa" plural) is a node on the tree of life. It is a group that includes all of the organisms classified in it. Consider the blue whale, or Balaenoptera musculus. It's genus, balaenoptera, is one taxon that it belongs to. It also belongs to the class taxon Mammalia, as it is a mammal.
iNaturalist is a wonderful tool and online community centered around crowd-sourcing observation and identification of organisms in nature. Darwin relies on the taxonomy framework that iNaturalist provides to determine how trees should be built. Using iNaturalist and Darwin, you can easily build phylogenetic trees of life you observe yourself, by first recording your observations to iNaturalist, and then importing them into Darwin.
No login to iNaturalist is needed. Simply select the iNaturalist icon in the Tree Builder, enter your username, and the number of observations you wish to load. For example, if you enter 10, your latest 10 observations will be loaded.
To save a tree, select the Share button and copy the tree URL. To access the tree in the future, use this URL - all of the tree data is encoded in the link. There is no database (currently) storing user-created trees, but this may be added in the future.
