New clues to how sex evolves

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have found clues to part of the complex question of how sex evolves, through ongoing studies of the nematode Caenorhabditis elegans. They have identified a key family of genes that code for closely related zinc-finger proteins that help bring C. elegans chromosomes together during meiosis, the specialized cell division that produces gametes, or sex cells.

1. Blood protein offers clues to heart attack in seemingly healthy people
   07-02-2007 · EurekAlert!
   We've all wondered how a seemingly healthy person can actually be at high risk for heart disease or a heart attack. Now researchers have uncovered a new clue to this mystery. The culprit: myeloperoxidase, a protein secreted by white blood cells that both signals inflammation and releases a bleach-like substance that damages the cardiovascular system.

2. No sex for 40 million years? No problem
   03-19-2007 · EurekAlert!
   A group of organisms that has never had sex in over 40 million years of existence has nevertheless managed to evolve into distinct species, says new research published today. The study challenges the assumption that sex is necessary for organisms to diversify and provides scientists with new insight into why species evolve in the first place.

   Evolutionary biologists have focused on sex differences since Darwin's "Origin of Species." A straightforward but seemingly underappreciated explanation for the ability of males to answer the call of sexual selection may be that their genetic machinery is simpler.

   Pregnancies in Jerusalem in the 1960s and 1970s may hold vital clues about how pancreatic cancer and diabetes are linked. According to research published in the online open access journal BMC Medicine, women with a history of gestational diabetes had a higher risk of developing pancreatic cancer later in life.

   03-22-2007 · EurekAlert!
   Why mitochondrial genes ditch their cushy haploid environs to take up residence in a large and chaotic nucleus has long stumped evolutionary biologists, but Indiana University Bloomington scientists report in this week's Science that they've uncovered an important clue in flowering plants.

6. How are phenotypic differences between sexes related to phenotypic variation within sexes?
   01-10-2007 · EurekAlert!
   It has long been recognized that sexually dimorphic traits -- traits that are systematically different between members of different sex in the same species, such as peacocks' tail feathers -- tend to vary a great deal among individual males, and that much of this within-sex variation depends on individual condition. Indeed, theory predicts that sexual dimorphism will evolve based on condition dependence so that, among traits, a more pronounced difference between male and female should be associated with a stronger response to variation in condition.

7. Evolution of the sexes: What a fungus can tell us

   Fungi don't exactly come in boy and girl varieties, but they do have sex differences. In fact, a new finding from Duke University Medical Center shows that some of the earliest evolved forms of fungus contain clues to how the sexes evolved in higher animals, including that distant cousin of fungus, the human.
