Generation

Generation (from the Latin generāre, meaning "to beget"), also known as procreation in biological sciences, is the act of producing offspring. In a more general sense, it can also refer to the act of creating something inanimate such as ideas, sound, electrical generation using technology or cryptographic code generation.

A generation can refer to stages of successive improvement in the development of a technology such as the internal combustion engine, or successive iterations of products with planned obsolescence, such as video game consoles or mobile phones.

In biology, the process by which populations of organisms pass on advantageous traits from generation to generation is known as evolution.
