Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual reproduction. Two novel hypotheses have been proposed that ...

The freshwater polyp Hydra oligactis is essentially immortal and reproduces asexually by cloning itself. Except when it gets too cold: then the animal switches to sexual reproduction, begins to age, ...

The fusion of two cells is a decisive event in the sexual reproduction of many organisms. In fungi, cells must not only bring ...

Studying a species of beetle mite, an international research team has demonstrated for the first time that animals can survive over very long periods of time (possibly millions of years) entirely ...

If you’ve ever had a spiny leaf insect as a pet, or you’re considering getting one, hopefully someone has warned you about this: if you put one in your enclosure, you might come back some time later ...

Recombination and sexual reproduction lie at the heart of evolutionary innovation, reshuffling alleles to generate genetic diversity and enabling populations to adapt to shifting environments. Meiotic ...

In the debate over human origins and the nature of sexual reproduction, religious and scientific perspectives often diverge. The Bible claims man came first, with women derived from man’s rib. Yet, ...

The evolution of sexual reproduction in living beings is one of the biggest mysteries in biology. There are two known modes of reproduction: asexual, where the organism creates clones of itself, and ...
