Researchers compared the whole genome sequence of two genetically distinct lineages of bed bug, and their findings indicate bed bugs may well be the first true...
Cold-adapted animals started to evolve 2.6 million years ago when the permanent ice at the poles became more prevalent. There followed a time when the continental...
New research shows that dentine, the inner layer of teeth that transmits sensory information to nerves inside the pulp, first evolved as sensory tissue in the...
A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing...
Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than...
Biologists recently announced that they have released the first broad scale, comparative, fine-grained analysis linking the amplitude, or volume, of a birds' song to its vocal...
To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA,...
Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The research not only adds a facet to possible evolutionary...
Scientists have decoded the atomic structure of Photosystem I from a 3-billion-year-old cyanobacteria lineage, offering a unique look at early oxygen-producing photosynthesis. The ancient nanodevice, purified...
The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce....
