Cephalopods—a class encompassing octopuses, squid, cuttlefish and nautiluses—exhibit extraordinary morphological innovation, ecological diversity and complex behaviours. Molecular phylogenetic ...

A ZSI study reveals India hosts 191 cockroach species, with over 60% endemic, emphasizing the need for genetic diversity ...

A spectacular dinosaur discovery in Spain is giving scientists a rare new look inside the world of stegosaurs.

Phylogeny, as a biological process, refers to the historical pattern of lineage splitting and character change that generates the evolutionary relationships among organisms or genes over time. It ...

It may sound too bizarre to be true, but the Amazon molly (Poecilia formosa), a fish that inhabits rivers, lakes, and swamps ...

Deep within a crop field in eastern Spain, paleontologists uncovered something they had almost given up hope of ever finding, ...

Eight meters above the forest floor in French Guiana, clinging to a branch in the humid tangle of the rainforest understory, ...

The flowering plants (angiosperms) represent the most species‐rich clade of land plants, with an estimated 300,000 species distributed across virtually every ecosystem. Phylogenetic diversity captures ...

Australia does not simply have a large number of lizards. In many regions, they dominate the landscape almost quietly, moving through scrub, rocks, and dry grass in numbers that become obvious only ...

In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry.

This diagram illustrates that lineage independence is not necessary for convergent evolution to occur. In classic convergent evolution, the precursor genetic material must occur on unrelated lineages.
