Latest Evolution Stories
Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy – known as selfing – guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations.
According to a new study, relatively newly acquired genes can quickly become a major part of an organism’s genetic machinery and even essential for life.
The study reveals how a genetic duplication that occurred millions of years ago encouraged the evolution of the ASF1b gene, involved in cancer development
Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years.
Many animals – from locusts to fish – live in groups and swarm, but scientists aren't sure why or how this behavior evolved. Now a multidisciplinary team of Michigan State University scientists has used a model system to show for the first time that predator confusion can make prey evolve swarming behavior.
The top 10 new species list was announced May 23 by the International Institute for Species Exploration at Arizona State University
Environment is not the only factor in shaping regulatory patterns — and it might not even be the primary factor, according to a new Rice University study that looks at how cells’ protein networks relate to a bacteria’s genome.
The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study.
These days, phylogeneticists – experts who painstakingly map the complex branches of the tree of life – suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings.
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...
