All the living things that we can see evolved from those that we can’t. Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled ...

Among these kingdoms, one stands out as encompassing the vast array of life, including seemingly disparate creatures like sea ...

Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when ...

Cells can evolve specialized functions under a much broader range of conditions than previously thought, according to a study. Cells can evolve specialised functions under a much broader range of ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

Bacteria are everywhere, even inside of our bodies, and they are thought to date back to the early days of life on Earth. These single-celled organisms are classified differently than animals' ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

THE genetic mechanisms in differentiative phenomena of bacterial cells have recently been elucidated in great detail by the work of Jacob and Monod 1–4. However, the differentiation of cells in ...

Cooperation is a classic solution to hostile environments that limit individual survival. In extreme cases this may lead to the evolution of new types of biological individuals (e.g., eusocial ...
