...comprehensive law to elucidate all the facts of change in the organic world. Wallace stated it simply: "Every species has come into existence coincident both in space and time with a preexisting closely allied species." The law was designed to explain the geographical distribution of animal and...

...In his 1855 paper, Wallace set out a series of propositions that led him to enunciate the law that "Every species has come into existence coincident both in space and time with a preexisting closely allied species", and to claim that his law led to a "true system of classification". "The pre-existing...

...New Species'; a law which came to be known as the Sarawak Law. The essence of the Sarawak Law is that 'every species has come into existence coincident both in space and time with a pre-existing closely allied species'. It was as close to an explanation of evolution as anyone had yet dared. Contrary...

It suggested...

...consistent with known patterns of geographical and geological distribution, Wallace concluded that "every species has come into existence coincident both in space and time with a pre-existing closely allied species." This remarkable argument combined geological history with the growing mass...

...or species has come into existence twice. 10. The following law may be deduced from these facts: — Every species has come into existence coincident both in space and time with a pre-existing closely allied species.10 So no one could miss his conclusion, Wallace punched it up with italics....

As Wallace himself famously put it, "Every species has come into existence coincident both in space and time with a pre-existing closely allied species." Yet the boundaries were far from self-evident. Darwin, for example, wavered...
