What is the tree of life in biodiversity?
Wherever they're found, all living things are related because they all share a common ancestor. To show how species are related, scientists create diagrams called cladograms. Like a family tree, a cladogram shows close and distant relatives. Scientists call the family tree for all species on Earth the "Tree of Life."
What is the tree of life theory?
The tree of life on Earth portrays the evolutionary relationships among groups of plants, animals and all other forms of life. Any one of those groups encompasses many subgroups, and each subgroup many individual species.
What is the tree of life model?
In this Tree of Life, time flows from the earliest at the bottom to the most recent at the top, as indicated by the arrow on the right. The branches represent all the groups of organisms that lived in the past. The groups listed at the top are those alive today.
How has the tree of life changed over time?
The tree of life as we know it has dramatically expanded due to new genomic sampling of previously enigmatic or unknown microbial lineages. This depiction of the tree captures the current genomic sampling of life, illustrating the progress that has been made in the last two decades following the first published genome.

Many animals do not age, and physiological mechanisms of aging vary across species. Nonetheless, conserved aging-related signalling pathways exist.
Animal life history is shaped by the pace of life and the distribution of age-specific mortality and reproduction · Biology, Environmental Science. Nature ...
Abstract: Evolution drives, and is driven by, demography. A genotype moulds its phenotype's age patterns of mortality and fertility in an environment; ...
On the other, many intermediate taxa across the tree of life appear not to age at all, and there is substantial variation in aging mechanisms and patterns, ...
This diversity challenges theoreticians to develop broader perspectives on the evolution of ageing and empiricists to study the demography of more species. more ...
It is therefore of utmost importance to identify and understand mechanisms of aging across the tree of life and translate these discoveries into health- ...
