Death by a Thousand Cuts? Not for Small Populations

Michigan State University

In a paper published in Nature Communications, Christoph Adami, Michigan State University professor of microbiology and molecular genetics, and graduate student Thomas LaBar have provided a look at how certain species survive by evolving a greater ability to weed out harmful mutations – a new concept called “drift robustness”.

Keratin, Pigment, Proteins from 54 Million-Year-Old Sea Turtle Show Survival Trait Evolution

North Carolina State University

Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54 million-year-old sea turtle hatchling. The work provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.

Risk of Caesarean Section Is Heritable

University of Vienna

Women born by Caesarean section due to a fetopelvic disproportion (FDP) are more than twice as likely to develop FDP when giving birth than women born naturally. This is the conclusion of a study by a team of evolutionary biologists at the University of Vienna headed by Philipp Mitteroecker. Using a mathematical model, the team was able to explain the paradoxical phenomenon that natural selection did not lead to the reduction in the rates of obstructed labour. Empirical data also support that the regular use of C-sections has already triggered an evolutionary increase of FPD rates.

UW Researchers Discover an Evolutionary Stepping Stone to Beet-Red Beets

University of Wisconsin-Madison

Writing this week (Oct. 9, 2017) in the journal New Phytologist, University of Wisconsin–Madison Professor of Botany Hiroshi Maeda and his colleagues describe an ancient loosening up of a key biochemical pathway that set the stage for the ancestors of beets to develop their characteristic red pigment.

Liverwort Genes and Land Plant Evolution

Lawrence Berkeley National Laboratory

An international team including DOE Joint Genome Institute researchers analyzed the genome sequence of the common liverwort (Marchantia polymorpha) to identify genes and gene families deemed crucial to plant evolution and have been conserved over millions of years and across plant lineages.

New Chameleon Species Discovered (Video)

University of Texas at El Paso

The Ph.D. candidate in UTEP’s Ecology and Evolutionary Biology program has discovered three new species of chameleons. The reptile trio, historically thought to be a single species, was found in different parts of the Albertine Rift in Central Africa.

Genes That Separate Humans From Fruit Flies Found

University of Portsmouth

Genes which determine animal complexity – or what makes humans so much more complex than a fruit fly or a sea urchin – have been identified for the first time.
