Spanning evolutionary biology, genetics, development, neurobiology, endocrinology and psychology, as well as current events and sports, students explore the complexities of the biology of sex.
Few animals have babies without sex, so biologists assumed asexual reproduction must have evolutionary drawbacks. But a self-cloning Australian grasshopper shows things might be more complicated.
A single seagrass plant in Shark Bay is around 4,500 years old, covers 200 square kilometres of seabed, and thrives in harsh conditions.
Perceptions about the role of sperm have changed over time, but asexual reproduction doesn’t need sperm for fertilization.
Asexuality is less about a traditional understanding of sexual attraction and behaviour, and more about being able to discuss likes and dislikes in the early stages of a relationship.
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?
There’s long been a lack of evidence for why sex has become so much more common than asexual reproduction across nearly all species. Thankfully, this is now slowly changing.
Nematodes, or roundworms, that undergo asexual reproduction, have only two-thirds as many active genes as related species…
Candida tropicalis cells, once thought to be asexual, have been discovered as being capable of mating sexually. Scientists…
