Evolutionary Theory: Scientists Examine Key Aspect Of Evolution

Researchers carried out a detailed study of the 'Meselson effect' where chromosomes in asexual organisms can evolve independently from each other and become quite distinctive over time. A parasite called 'Trypanosoma brucei gambiense' was used to carry out the study.

Polar Bear Y Chromosome Reconstructed: What DNA Reveals About Endangered Species

Scientists have reconstructed part of the male chromosome in polar bears and have found out why the Y chromosome is so important.

Why Men Have a Shorter Lifespan than Women

It's well known that men have shorter life expectancies than women--but why is that the case? A recent study has found that there's a correlation between a loss of the Y chromosome in blood cells and a shorter life span in men.

The Y Chromosome is Here to Stay with Stable Genes: Men are Not Disappearing

The male chromosome in humans, the Y chromosome, has had a history of dramatic genetic decay. Despite this, though, it's managed to preserve a small set of genes. Now, researchers have found that these genes ensure not only the chromosome's survival, but also the survival of men in general.

Origins of Y Chromosome Revealed: Male 'Genetics' Emerged 180 Million Years Ago

We all know that while there are many differences between men and women, the main element boils down to the genome: the Y chromosome. Now, though, researchers have found exactly when the Y chromosome first emerged in our evolutionary history, revealing a bit more about men.

Male Chromosome is Not Dying Out: Y's Demise Not Inevitable

Is the Y chromosome doomed to disappear? That's not the case, according to a new study. Scientists have found that the common notion that the Y's genes are mostly unimportant and that the chromosome is destined to dwindle and disappear is actually untrue.

Revolutionary Technology Reveals How Cancer Chromosome Abnormalities Form in Cells

For the first time, scientists have directly observed events that lead to the formation of a chromosome abnormality that is often found in cancer cells. The abnormality, called a translocation, occurs when part of a chromosome breaks off and becomes attached to another chromosome.
