Latest Evolution Stories
A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not only in how animals' skull and jaw are shaped, but how this leads to different feeding strategies to exploit different ecological niches.
A team of Belgian biologists led by researchers at KU Leuven has provided the first genetic evidence that rapid evolution can help non-native plant species spread in new environments.
Mutations in genes involved in cardiovascular function allowed polar bears to rapidly evolve the ability to consume a fatty, blubber-rich diet without developing high rates of heart disease, an international team of scientists reported this week in the journal Cell.
Along with our big brains and upright posture, thick tooth enamel is one of the features that distinguishes our genus, Homo, from our primate relatives and forebears.
Populations of predators and their prey usually follow predictable cycles.
The robust defenses that yeast cells have evolved to protect themselves from environmental threats hold lessons that can be used to design computer networks and analyze how secure they are, say computer scientists at Carnegie Mellon University.
Take a muscle cell, modify it over millions of years, and you end up with an exciting and literally shocking evolutionary result: the electric fish.
Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve.
Manure from dairy cows, which is commonly used as a farm soil fertilizer, contains a surprising number of newly identified antibiotic resistance genes from the cows' gut bacteria.
Domestication genes tend to be insensitive to the rest of the genome and to the environment. Could finding this subset of robust genes have slowed things down?
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
- A transitional zone between two communities containing the characteristic species of each.
