In our interactive tree of life you can explore the relationships between 2,235,473 species and wonder at 105,463 images on a single zoomable page. Each leaf represents a different species, and the branches illustrate how these many species evolved from common ancestors over billions of …

The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859).

Oct 19, 2023 · A phylogenetic tree shows the evolution of relationships among different organisms.

OneZoom is a freely available Tree of Life, connecting all species together in a spiraling beanstalk that shows evolutionary history. Each leaf on the OneZoom tree represents a species and the branches show how they are connected through evolution.

Documenting the broad evolutionary history of animal, or Metazoan, life has been a central goal of biology and paleontology since the early work of Lamarck (1744–1829) and Ernst Haeckel (1834–1919). Numerous competing hypotheses of relationships amongst the 30-some recognized animal phyla have been developed over the past two centuries ...

Oct 18, 2016 · The power of that idea can be seen today in the ubiquity of evolutionary trees (also called phylogenetic trees) in all biological disciplines, from studies of newly discovered species to cutting-edge cancer research.

Dec 19, 2021 · Spiraling fractal branches draw connections between a staggering 2.2 million living species on Earth in the most comprehensive tree of life ever created. "It allows people to find their favorite living things, be they golden moles or giant sequoias, and see how evolutionary history connects them together to create a giant tree of all life on ...

modern science is the realization that all life, from the smallest microorganism to the largest vertebrate, is connected through genetic relatedness on a vast evolutionary tree. This Tree of Life provides the framework for much of our modern understanding of biology because it reveals the

The evolution of animals – the Metazoans – as shown by the fossils of the Burgess Shale is a comparatively recent phenomenon. Sponges and radially-symmetrical animals probably evolved during the Ediacaran Period (635-542 million years ago).
