Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch ...

Comb jellies "could repurpose [their] genetic toolkit in different ways like a Swiss knife," said the researchers.

By combining data on all known bird species, this tree is the most impressive snapshot yet of one of Earth’s most awe-inspiring classes of animal.

An international collaboration has published groundbreaking research, shedding light on the most significant increase in complexity in the history of life's evolution on Earth: the origin of the ...

“The evolutionary history of genes is ... advantages here is applying the gene‑tree species‑tree reconciliation approach to such a diverse dataset representing the primary domains of life, Archaea and ...

The greatest amount of biological activity and the largest diversity of species and genes, however, come from the other four kingdoms science now recognizes: bacteria, archaea (a less-studied ...

Approach: Using bioinformatics tools, we reconstructed clonal evolution trees from whole-genome sequencing (WGS) analysis of tumors and inferred migration patterns to determine metastatic seeding.

Could aquatic mammals, such as whales, orcas, and bottlenose dolphins, ever evolve to live on land again? It seems the chances of this are actually vanishingly small, as the adaptations that allow ...

However, the adaptive value, mechanistic diversity, and evolution of epigenome-targeted DNA repair systems across the tree of life remain unresolved. Here, we investigated the evolution of histone ...

An ant preserved in 16 million-year-old amber mastered the art of camouflage. A rare 16 million-year-old ant preserved in amber is helping scientists uncover new secrets about one of nature's most ...

the billions of years that have passed since the fusion of an archaea and a bacteria have resulted in a lack of evolutionary intermediates in the phylogenetic tree until the emergence of the ...
