From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms ...

Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, Bart Kempenaers and colleagues from the Max ...

A small international team of animal behavior researchers has found that species of glass frogs whose males help care for offspring tend to have smaller testes than species whose males do not help care for offspring. In their ...
Picky female sparrows may be more unfaithful, new Imperial research suggests. Cheating on social partners is common in birds, and there are clear benefits to males who can raise more offspring without investing in their care. ...

In primates, the biggest, bossiest males usually get to father the most offspring; and for a long time it was thought that this rule applied to orangutans too. Male orangutans openly compete; and it's the older males with ...

In biology, offspring is the product of reproduction, a new organism produced by one or more parents.
Collective offspring may be known as a brood or progeny in a more general way. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all the offspring, as with the honeybee.
Human offspring (descendants) are referred to as children (without reference to age, thus one can refer to a parent's "minor children" or "adult children"); male children are sons and female children are daughters. See kinship and descent.
The word "fetus" is derived from the Latin word for "offspring." In humans, the fetal stage begins eight weeks after conception, when all of the major organs have been formed.
