Using 200 fossils, the researchers traced their tree of life back in time to show how flowering plants evolved over geological time. They found that early flowering plants did indeed explode in diversity, as Darwin noted. The rapid development of these plants gave rise, shortly after their origi...
regional tree of lifeSoTreevascular plantsp>We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using sequences of the chloroplast genes atpB , matK , ndhF , and rbcL and mitochondrial matR . We produced a matrix comprising 6098 species and including 13695 DNA sequence...

The "grotesque" baobab tree has long been known as the "tree of life" for its ability to create and maintain its own ecosystem in arid regions. Since the time of the ancient Egyptians, people have marveled at what researchers say is among "the most charismatic species on our planet," but...
of its DNA, were able to place it on the tree of life. The team even analyzed extinct plants, such has the Guadalupe Island olive (Hesperelaea palmeri), which has not been seen alive since 1875. In fact, 511 of the species sequenced are already at risk of extinction, according to ...
Organisms in the domain Eukarya include animals, plants, fungi, and algae.What are the Domains of Life? All living things can be broadly grouped into three overall domains of life. Organisms are categorized into each domain based on key differences that define each. The three domains of life ...
The days are markedly shorter, the nights cooler, and our winter gear can soon make its way into our wardrobes for daily use. Our plants are in transition too, breathing a sigh of relief after those brutal heat waves last summer. Native plants literally spring to new life with the first...
The baobab tree is sometimes called “the Tree of Life." Baobabs grow in Africa and Australia. They are the most famous trees in Africa. Baobabs have very thick, wide trunks (树干).Often the trunks have large empty spaces inside. In South Africa, one famous tree had a hole so large ...
On the one hand, it is therefore important to preserve the Tree of Life simply because there is so much hidden, as-of-yet untapped medical value in the species that compose the Tree of Life. Numerous chemical compounds of direct medical value to our own species await discovery. Plants, ...
The tree of life is one of the most important organizing principles in biology1. Gene surveys suggest the existence of an enormous number of branches2, but even an approximation of the full scale of the tree has remained elusive. Recent depictions of the tree of life have focused either on...
