The Tree of Life for the natural sciences provides a metaphor for evolution and descent with modification, an organizing structure for the biological diversity that we see on earth, and a hypothesis for how evolution processes lead to diversification patterns. The meaning and the methods for ...
The successful colonization of new habitats has played a fundamental role during the evolution of life. Salinity is one of the strongest barriers for organisms to cross, which has resulted in the evolution of distinct marine and non-marine (including bot
THE TREE OF LIFE One of the principal ongoing projects of modern biology is the construction of a comprehensive tree of life showing evolutionary relationships. Early attempts at finding the relationships among taxa were based on morphological characters and had many successes, as in sorting out the...
There can scarcely be a better way to decorate a blank wall or disguise a household imperfection than to cover it with a tree of life tapestry. "Tree of Life" is an almost universal religious theme that can be found in beliefs ranging from primitive to m
About 3.6 billion years ago there was a species that eventually gave rise to all of life we have on Earth today; that species was the last universal common ancestor, or LUCA. (The ancestors of LUCA were themselves universal common ancestors, but they were not the last such ancestor. There...
of life onEarthis perhaps not fully appreciated. The biosphere is dependent on the metabolism, death, and recycling of plants, especially trees. Their vast trunks androotsystems storecarbon dioxide, move water, and produce oxygen that is released into the atmosphere. The organic matter of the ...
“I am a spirit, I am full of life and love and peace and purity”, you say “no flesh, I am not submitting to your selfish, impure, ungodly desire, you do not get to control my life and push me into immoral thoughts. Flesh, you are crucified, and you have no strength to tell...
Cell-in-cell events are found across the tree of life, from some unicellular to many multicellular organisms, including non-neoplastic and neoplastic tissue. Additionally, out of the 38 cell-in-cell-related genes found in the literature, 14 genes were over 2.2 billion years old, i.e., ...

Human-driven extinction threatens entire lineages across the Tree of Life. Here we assess the conservation status of jawed vertebrate evolutionary history, using three policy-relevant approaches. First, we calculate an index of threat to overall evolutio
