Self-replication
Self-replication is any behavior of a dynamical system that yields construction of an identical copy of itself. Biological cells, given suitable environments, reproduce by cell division. During cell d...

5 Gross And Amazing Ways Animals Deliver Sperm
One worm lives inside the female and ejaculates through the top of her head. In some deep-sea anglerfish species, like the needlebeard seadevil, the tiny male bites into the female, who is often 10 ti...
Stressed Dads Affect Offspring Brain Development Through Sperm MicroRNA
More and more, scientists have realized that DNA is not the only way that a parent can pass on traits to their offspring. Events experienced by a parent over a lifetime can also have an impact. Now Un...
Scientists Discover How Some Of The World’s First Animals Reproduced
Rangeomorphs, which lived about 565 million years ago, were pretty strange. They're often considered to be some of the first animals to evolve on Earth, but they share little in common with modern cri...
Researchers develop first single-molecule LED
The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: Scientists have developed the first ever single-molecule LED. The device is formed from a single polythi...

Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse. The term superfecundation is derived from fecund, meaning the ability to...
Fertilisation
Fertilisation or fertilization (also known as conception, fecundation and syngamy) is the fusion of gametes to initiate the development of a new individual organism. In animals, the process involves t...
