SENI Biometric Analysis on the extinct Scincidae species: Macroscincus coctei (underlined)
The SENI is a ratio based on anterior foot length at the junction of the

ulna/radius-carpal bones to the longest digit divided by the snout to vent

length {SVL} (B. Schnirel, 2003). It had been determined that a

relationship seemed to exist between

The facts of evolution: fighting the Endarkenment
Those of us who practice experimental science are living in the best of times and the worst of times, and I’m not talking about A Tale of Two Cities, but a tale of two cultures

Spatial mosaic evolution of snail defensive traits
The authors addressed certain questions concerning the evolution of defenses in Mexipyrgus.

Evolution and medicine: the long reach of "Dr. Darwin"
In this review the authors consider the new science of Darwinian medicine.

Chromatin structure and evolution in the human genome
Evolutionary rates are not constant across the human genome but genes in close proximity have been shown to experience similar levels of divergence and selection.

Evolution of male genitalia: environmental and genetic factors affect genital morphology in two Drosophila sibling species and their hybrids
In this work the authors investigated the patterns of intraspecific variation and interspecific divergence in male genitalic morphology (size and shape) in the cactophilic sibling species Drosophila buzzatii and D. koepferae.

Ancient ape ruled out of man's ancestral line
Ancient remains, once thought to be a key link in the evolution of mankind, have now been shown to be 400,000 years too young to be a part of man's family tree.

Finding an answer to Darwin's Dilemma
Oxygen may be the clue to first appearance of large animals...

A new male-specific gene in algae unveils an origin of male and female
Researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells.

Does evolution select for faster evolvers?
It's a mystery why the speed and complexity of evolution appear to increase with time.

Europeans' understanding of science, evolution, more advanced than Americans
Only about 40 percent of American adults accept the basic idea of evolution, a figure much lower than any European country.

Man's best friend lends insight into human evolution
Flexibly drawing inferences about the intentions of other individuals in order to cooperate in complex tasks is a basic part of everyday life that we humans take for granted.

Flowers shape themselves to guide their pollinators to the pollen
Wide flowers for bats, narrow flowers for hummingbirds in the cloudforests of Ecuador

MIT's ocean model precisely mimics microbes' life cycles
Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs

Robust time estimation reconciles views of the antiquity of placental mammals
Despite great progress over the past decade, the evolutionary history of placental mammals remains controversial.

Sea snails break the law
Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated.

Neutral evolution has helped shape our genome
Researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

How E. coli evolves to adapt to changing acidity
One in a series of studies on laboratory studies of selection and evolution

Origins of nervous system found in genes of sea sponge
Scientists have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge
