Feedbacks and the coevolution of plants and atmospheric CO2
A systems analysis of the physiological and geochemical processes involved was presented, identifying new positive and negative feedbacks between plants and CO2 on geological time scales.

Leaf Evolution: Gases, Genes and Geochemistry
This Botanical Briefing reviews how the integration of palaeontology, geochemistry and developmental biology is providing a new mechanistic framework for interpreting the 40- to 50-million-year gap between the origination of vascular land plants and the a

How Did Bilaterally Symmetric Flowers Evolve From Radially Symmetric Ones?
How did bilaterally symmetric flowers evolve from radially symmetric ones?

Water Lily May Provide A "Missing Link" In The Evolution Of Flowering Plants
One of the great mysteries of evolutionary biology is how, 150 or more million years ago, modern-day angiosperms (flowering plants) diverged from their closest relatives, the gymnosperms

Tiny Tampa Bay Fish Key To Evolution Of Immune System
Scientists studying a tiny primitive fish in Tampa Bay now say they have found the "missing link" marking the point in evolution that led to the development of the modern-day human immune system.

New Cellular Evolution Theory Rejects Darwinian Assumptions
The driving force in evolving cellular life on Earth has been horizontal gene transfer, in which the acquisition of alien cellular components work to promote the evolution of recipient cellular entities, says microbiologist.

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.

Wisconsin Scientists Find Portal To Show Animals Evolve
The bachelor fruit fly is in a race against time to mate and pass along its genes.

Study Suggests Humans Can Speed Evolution
Study suggests that humans may have sped up the evolutionary clock for one species of fish.

Mouse study suggests mammoth evolutionary change
Biologists has found evidence of dramatic evolutionary change in a span of just 150 years, suggesting genetic evolution can occur a lot faster than many had thought possible.

Trees, Vines And Nets -- Microbial Evolution Changes Its Face
EBI researchers have changed our view of 4 billion years of microbial evolution.

Experimental Evolution of Yeast in the Lab May Illuminate Early Events in Speciation
By experimentally promoting rapid, small-scale evolution within a lab population of yeast, researchers have shed light on the kinds of genetic changes that may underlie the emergence of new species.

Subspecies comparison of the Genus: Corucia
This is the most detailed description of the two subspecies of Corucia zebrata (underlined), the monkey tailed skink, including new information not previously submitted. Previously, this information has been cryptic, at best.

About the evolution in Islands and in the mainland

The Context of Human Genetic Evolution
The debate on modern human origins has often focused on the relationship between genes and fossils.

Promiscuity May Be Key Factor In Immune System Evolution, Study Suggests
A new study indicates that evolution of the immune system may be directly linked to the sexual activity of a species.

The First Laugh: New Study Posits Evolutionary Origins Of Two Distinct Types Of Laughter
In an important new study from the forthcoming Quarterly Review of Biology, biologists from Binghamton University explore the evolution of two distinct types of laughter -- laughter which is stimulus-driven and laughter which is self-generated and strateg

Sex, cleaner of genomes
The finding supports a hypothesis that sex is an evolutionary housekeeper that adeptly reorders genes and efficiently removes deleterious gene mutations. The study also suggests sexual reproduction maintains its own existence by punishing, in a sense, ind
