Dark centers of chromosomes reveal ancient DNA

Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have ...

Researchers gain insight into chromosome evolution in flies

NC State University researchers have shed new light on the evolution of fly chromosomes by identifying a gene indispensable for male survival in a devastating livestock pest species. What they found could have important implications ...

Knowledge gap on the origin of sex

There are significant gaps in our knowledge on the evolution of sex, according to a research review on sex chromosomes from Lund University in Sweden. Even after more than a century of study, researchers do not know enough ...

Was the dawn of man among trees in the cradle of disease?

A student-led conference to be webcast live will ask, in light of recent research, whether the story of human origin is radically different from established thinking, and what that might mean for everything from genetics ...

Advance in chromosomal evolution in sea cradles

A chromosomal study performed in a common Mediterranean chiton (sea cradle) provides information, relevant to systematic relationships of the species; furthermore the comparison of its karyotype with ones in literature allows ...

Compelling evidence that brain parts evolve independently

An evolutionary biologist at the University of Manchester, working with scientists in the US, has found compelling evidence that parts of the brain can evolve independently from each other. It's hoped the findings will significantly ...

Scientists peek at the early evolution of sex chromosomes

Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings are described ...

Sex chromosome evolution tracked in fruit fly

(Phys.org) -- Fruit flies are commonly used in genetics research because their lifespan is short, they are easy to breed in the laboratory, and mutants are widely available. There are about 1,500 known species. Now a new ...
