Birds have some of the most amazing sex differences of any animal. They can control the sex of offspring, and even produce rare half-male, half-females. And their sex genes and chromosomes are quite different from ours.

It’s not about trauma or how you were raised: evidence now points to a biological basis for transgender, and to the action of particular genes in that determination.
Secara biologis, seks mulai terbentuk saat Anda hanyalah seonggok kecil sel yang berada di uterus ibu.
There are many cultural and social factors involved in making a baby into a man or a woman. But biologically speaking, sex starts when you’re just a tiny group of cells in your mother’s uterus.
The koala genome, published today, gives us new and valuable information to aid conservation of this marsupial. It identifies special genes that evolved to adapt the koala to its unique lifestyle.
A new paper describes the idea of “genetic nurture”, where parents’ genes, even those not passed on to their child, have major effects on kids’ health and educational attainment.
Bagi seorang ahli genetika evolusi, gagasan bahwa susunan genetika seseorang mempengaruhi preferensi pasangannya tidaklah mengejutkan.
Like it or not, evidence now shows that men and women differ genetically far more profoundly that we previously recognised. An analysis from the 2017 winner of the Prime Minister’s Prize for Science.
The 2017 Prime Minister’s Science Prize winner is genetic researcher Professor Jenny Graves, well known for her 2002 suggestion that the male Y chromosome will self-destruct.
Epigenetics is consistent with the theory of evolution – in fact, Darwin predicted that tiny parcels might somehow provide a flow of information from experience to inheritance.
How new species are created is at the core of the theory of evolution. Mammals may be a good example of how sex chromosome change drove major groups apart.
Rotifers are tiny creatures found in ponds or puddles and can reproduce without sex. The theory says they should not have survived so how have they done it?
Many babies are born with a genetic variant that can result in the child being neither a typical boy or girl. There has been considerable debate about whether the child should be treated.
Scientists have discovered the genetic “switch” that causes many animals, including fish, frogs and humans, to look the same at a certain point in embryonic development.
Genetically modified animals can help to feed the world’s burgeoning population, but there is still a lot of misinformation concerning its safety.
You might be surprised to hear that virgin births are possible - just not in humans. By the reason why remains an evolutionary mystery.
What produces the differences between men and women? Are they trivial or profound? Are they genetic or environmental, or both? And are men really closer genetically to chimpanzees than to women?
Mate choice is one of the most highly selected traits in any animal. Just ask a fruitfly, which devotes a large share of its genes to choosing and attracting a mate.
The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we’ve seen it…
The claim that homosexual men share a “gay gene” created a furore in the 1990s. But new research two decades on supports this claim – and adds another candidate gene. To an evolutionary geneticist, the…
