Quick Take Boulenger’s backpack frog carries eggs in a dorsal pouch on its back instead of dropping them into water. This ...

The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown.

One of the most enduring, basic questions of life is: How does it happen? For instance, in human development, how do cells self-organize into skin, muscles or bones? How do they form a brain, a finger ...

The evolution of a group of muscled frogs scattered throughout Asia is telling geologists about the sequence of events that led to the rise of the Himalayas and the Tibetan plateau starting more than ...

Evolution is the result of environmental pressures forcing species to adapt, and few environments exert pressures like the Chernobyl exclusion zone. A new study has revealed evolution in action as ...

Over the course of 500 million years, three species of poison frogs evolved to withstand a toxin they use to prevent predators from catching them. But, there’s a catch: the frogs experience a ...

Evolution, Vol. 75, No. 12 (DECEMBER 2021), pp. 3203-3213 (11 pages) Dollo’s law of irreversibility states that once a complex structure is lost, it cannot be regained in the same form. Several ...

Researchers analyzed CT scans of nearly every living amphibian genus to reveal that frogs have lost teeth over 20 times during their evolution, more than any other vertebrate group. Scientists have ...

Random walks constitute one of the most fundamental models in the study of stochastic processes, representing systems that evolve in a sequence of random steps. Their applications range from modelling ...

Germán Orizaola receives funding from the Spanish Ministry of Science and Innovation through the "Ramón y Cajal" Programme (RyC-2016-20656), the British Ecological Society (SR20-1169) and the Spanish ...
