Smithsonian's National Museum of Natural History reveals ants as fungus farmers
It turns out ants, like humans, are true farmers. The difference is that ants are farming fungus.   view more (2008-03-25)

Researchers sequence the basal eukaryote Tetrahymena thermophila
In an effort to improve our understanding of eukaryotic evolution, a team of over 50 researchers led by Jonathan Eisen sequenced the macronuclear genome of the single-celled ciliate Tetrahymena themophila.   view more (2006-08-29)

Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA... view more (2006-03-28)

Butterfly restrains Darwin
In experiments with butterflies, evolutionary biologists from Leiden University have demonstrated that natural selection is not always the only factor which determines the appearance of an organism. Constraints also appear to play a role at times in determining the progress and outcome of the... view more (2002-10-24)

Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of... view more (2008-08-19)

First 'rule' of evolution suggests that life is destined to become more complex
In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex.   view more (2008-03-18)

Unlocking The Secrets Of Evolution
Exactly fifty years ago, Watson and Crick revealed the structure of DNA, unleashing a scientific revolution. On the anniversary of that momentous discovery, the world's leading science journal, Nature, will publish new and groundbreaking genetic research by Bangor University scientist, Dr. Isabelle... view more (2003-03-06)

Third primate genome, the rhesus macaque, helps illuminate what makes us human
Researchers have sequenced the genome of the relatively ancient rhesus macaque (Macaca mulatta), providing perspective into how humans are genetically different from our primate relatives.   view more (2007-04-13)

Iowa State researcher studies gene families to explore diversity and evolution
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve.   view more (2006-08-01)

Insight into our sight: A new view on the evolution of the eye lens
The critical component in focusing is the eye lens, and the physical properties that underlie the transparency of the lens, as well as its ability to precisely refract light, arise from the high concentrations of special proteins called crystallins found in lens cells.   view more (2005-09-23)

The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found.   view more (2007-08-28)

Human culture subject to natural selection, Stanford study shows
The process of natural selection can act on human culture as well as on genes, a new study finds.   view more (2008-02-19)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases.   view more (2007-12-21)

A new tribe at the BA festival
A new tribe is emerging from Mexico's scorched earth. A team of geoarchaeologists working on a programme investigating human evolution have found skeletal remains in the desert of the Baja California Peninsula that give rise to new theories on the colonisation of the Americas.   view more (2004-09-03)

Fruitfly study shows how evolution wings it
In the frantic world of fruitfly courtship, the difference between attracting a mate and going home alone may depend on having the right wing spots.   view more (2006-04-20)

Animals can change genes quickly to keep up with viral ingenuity
Viruses are famous for evolving quickly, but the organisms they infect can't be expected to sit idly by.   view more (2006-03-21)

Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University... view more (2008-11-11)

Oxygen triggered the evolution of complex life forms
Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier than was thought, and in parallel with the availability of oxygen as an energy source. In the largest... view more (2004-01-22)

Survival of the fittest: even cancer cells follow the laws of evolution
Scientists from The Institute of Advanced Studies at Princeton and the University of California discovered that the underlying process in tumor formation is the same as for life itself-evolution.   view more (2008-08-04)

KGI professor contributes new insights on 'jumping genes'
Keck Graduate Institute (KGI) today announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes."   view more (2007-10-09)

Novel experiment documents evolution of genome in near-real time
A team led by bioengineering researchers at UC San Diego report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days.   view more (2006-11-06)

Molecular evolution of influenza A viruses circulated in Fujian Province, China
Fujian Center for Disease Control & Prevention, China, reported the molecular evolution of influenza A (H3N2) viruses in Fujian Province, south of China during the period 1996 - 2004 and demonstrated some key codons responsible for antigenic drift. The study is reported in Issue 51 (April,... view more (2008-04-01)

UCI scientists reconstruct migration of avian flu virus
UC Irvine researchers have combined genetic and geographic data of the H5N1 avian flu virus to reconstruct its history over the past decade. They found that multiple strains of the virus originated in the Chinese province of Guangdong, and they identified many of the migration routes through which... view more (2007-03-06)

Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative... view more (2004-12-20)

Scientists uncover the source of an almost 2 billion year delay in animal evolution
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly two billion years.   view more (2008-03-27)
