Teenagers often wonder how they can circumvent the outdated commandments handed down by their parents. Lacking a conscience, one tiny protozoan resolves the issue forcefully, dissolving many of its parents' genes as it charts its own course, according to new research.

"We've found the protein machinery a protozoan uses to turn off, and get rid of, unwanted genes," says C. David Allis of the University of Rochester (N.Y.). He and his colleagues at Rochester and at the Fred H...

The problem of the evolution of sex.(Evolution: A Molecular Point of View)(includes discussion)
The Biological Bulletin ; The unsolved problem of the evolution of sexual reproduction has been almost exclusively in the domain of population genetics. This suggests that new approaches may be fruitful; here I develop a molecular and phylogenetic framework. The problem Sexual reproduction is the cyclic alternation of (i)
Gene Expression Profiling Using cDNA Microarray Analysis of the Sexual Reproduction Stage of the Unicellular Charophycean Alga Closterium peracerosum-strigosum-littorale Complex1[W]
Plant Physiology ; The desmid Closterium peracerosum-strigosum-littorale complex, which is the closest unicellular sister to land plants, is the best characterized of the charophycean green algae with respect to the process of sexual reproduction. To elucidate the molecular mechanism of intercellular communication
At last, the scientists can tell us why we make love Proof that the mating game helps a species to survive
Daily Mail ; FOR most of us, the question of why we make love is either blindingly obvious or too imponderable to put into words. Either way, it is probably the least of our concerns at the time. But scientists think they have found the answer and it's not just that when it comes to making babies, it takes two

Differences in associated crustacean fauna and seasonality of sexual reproduction between two color morphs of the photosymbiotic ascidian Didemnum molle (Ascidiacea: Didemnidae) (1).
Pacific Science ; Abstract: Photosymbiotic ascidians inhabiting subtropical waters tend to have gonads in spring and summer, whereas those in tropical waters are usually sexually mature year-round. We studied the seasonality of sexual reproduction in two populations of the photosymbiotic ascidian Didemnum molle
Science: What's the use of sex, anyway?
The Independent - London ; WITH ALL the fuss over cloning this week it's worth asking the question: what do males contribute to sexual reproduction? Yes, I know they provide the sperm to fertilise the egg and a little paternal care for the offspring. But from the viewpoint of evolution, sex is a very expensive way to
Giardia bares all: parasite genes reveal long sexual history.(This Week)
Science News ; While it hasn't yet been caught in the act, a single-celled parasite has been ready for sex for billions of years. A new research finding provides evidence that sexual reproduction started as soon as life forms that have nuclei and organelles within their cells branched off from their structurally
