Rice's origins point to China, genome researchers conclude

  • PDF
1000pa (May 3, 2011) — Rice originated in China, a team of genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing. Their findings, which appear in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China....

Lichen evolved on two tracks, like marsupials and mammals

  • PDF
1000pa (May 3, 2011) — Lichen -- those drab, fuzzy growths found on rocks and trees -- aren't as cuddly and charismatic as kangaroos or intriguing as opossums, but they could be a fungal equivalent, at least evolutionarily.

A Duke research team has found that lichen that seem identical in all outward appearances and produce the same internal chemicals are in fact two different species, one living in North America and one in Australia....

Mutations in single gene may have shaped human cerebral cortex

  • PDF
1000pa (Apr. 28, 2011) — The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers led by the Yale School of Medicine and three other universities.

The findings, reported April 28 in the American Journal of Human Genetics, are based on a genetic analysis of in one...

Evolution in the back yard: Census of 750,000 banded snails leads to surprising results

  • PDF
1000pa (Apr. 27, 2011) — Thousands of members of the public across Europe have taken part in one of the largest evolutionary studies ever, by observing banded snails in their gardens and open public spaces.

More than 6,000 people in 15 European countries took part in the Open University's citizen science project between April and October 2009.

The project, Evolution MegaLab, is an online mass public experiment aimed at bringing Darwinian...

Out of Africa: How the fruit fly made its way in the world

  • PDF
1000pa (May 22, 2011) — The fruit fly Drosophila melanogaster used to be found only in sub-Saharan Africa, but about 10,000 years ago it began to colonize Asia and Europe. This period saw the start of human agriculture and the domestication of cats and oxen, but we have no evidence to suggest that early agricultural practices were associated with significant global warming. So, the fly's northerly spread is thought to relate to genetic...

Ancestors of land plants revealed

  • PDF
1000pa (May 2, 2011) — It was previously thought that land plants evolved from stonewort-like algae. However, new research published in BioMed Central's open access journal BMC Evolutionary Biology shows that the closest relatives to land plants are actually conjugating green algae such as Spirogyra.

Ancestors of green plants began to colonise the land about 500 million years ago and it is generally accepted that they evolved from...

Evolution: Not only the fittest survive

  • PDF
1000pa (Mar. 29, 2011) — Darwin's notion that only the fittest survive has been called into question by new research published in the journal Nature. A collaboration between the Universities of Exeter and Bath in the UK, with a group from San Diego State University in the US, challenges our current understanding of evolution by showing that biodiversity may evolve where previously thought impossible.

The work represents a new approach to...

Flowering plant study 'catches evolution in the act'

  • PDF
1000pa (Mar. 18, 2011) — A new University of Florida study shows when two flowering plants are crossed to produce a new hybrid, the new species' genes are reset, allowing for greater genetic variation.

Researchers say the study, to be published March 17 in Current Biology, could lead to a better understanding of how to best grow more stable and higher yielding agricultural crops.

"We caught evolution in the act," said Doug Soltis, a...

Abundant ammonia aids life's origins

  • PDF
1000pa (Mar. 7, 2011) — An important discovery has been made with respect to the possible inventory of molecules available to the early Earth. Scientists led by Sandra Pizzarello, a research professor at Arizona State University, found large amounts of ammonia in a primitive Antarctic asteroid. This high concentration of ammonia could account for a sustained source of reduced nitrogen essential to the chemistry of life.

The work is being...

Obesity and diabetes are a downside of human evolution, research suggests

  • PDF
1000pa (Feb. 25, 2011) — As if the recent prediction that half of all Americans will have diabetes or pre-diabetes by the year 2020 isn't alarming enough, a new genetic discovery published online in the FASEB Journal provides a disturbing explanation as to why: we took an evolutionary "wrong turn." In the research report, scientists show that human evolution leading to the loss of function in a gene called "CMAH" may make humans more prone...

Oldest fossils of large seaweeds, possible animals tell story about oxygen in an ancient ocean

  • PDF
1000pa (Feb. 19, 2011) — Almost 600 million years ago, before the rampant evolution of diverse life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche under the sea near what is now Lantian, a small village in Anhui Province of South China. Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free...
