 Rare Earth hypothesis - Wikipedia, the free encyclopedia
The rare Earth hypothesis is a response to the Fermi paradox which explains why we might expect a planet such as Earth to be very rare.
In the Earth, the cores of the original planet and an impacting body are thought to have merged to form an over-massive core that produces a powerful magnetic field to protect against solar radiation.
For example, in the Earth's case, a Mars-sized body might be required to impact it (as postulated by the Giant impact theory).

 Rare earth - Wikipedia, the free encyclopedia
Strictly speaking, a rare earth is an oxide of a rare earth element.
However, often rare earth elements themselves are loosely called "rare earths", and moreover the term is deprecated by IUPAC.
The correct term for these used by many chemists is Rare terrestrials.

 SETI Book Review: Rare Earth
The rare earth theory is that though bacterial life may be common in the universe, intelligent life -- in the form of terrestrial animals and plants -- is unique.
Rare Earth is organized in the traditional trajectory of such books, tracing the terms of the much-(ab)used Drake equation.
In Rare Earth, the authors present the theories they favor as complete and widely accepted, masking the fact that many are controversial (for example, whether star metallicity is as rare as they describe and whether Cambrian Ediacarans represent additional extinct phyla).

 Rare Earth: Why Complex Life is Uncommon in the Universe
In their book Rare Earth, published by Copernicus Press in 2000, Peter Ward and Donald Brownlee point at Drake's (and other physicists') mistakes in a long and depressing discussion, a discussion that took the wind out of more than one SF author's sail.
The evolution of life on Earth included some surprising leaps; two worth mentioning are the move from simple, single-cellular life to cells which contain internal organs, and the appearance of calcium-based skeletons.
The hypothesis claims that the conditions for creating complex life are rare; but we know for a fact that at least in one case, all the required conditions were met.

Rare Earth, a science book written by two of my University of Washington colleagues, geologist Peter Ward and astronomer Don Brownlee (WandB) depicts our galaxy as a lonely place dotted with hostile lifeless planets orbiting stars that are mostly too hot, too cold, too unstable, or too short-lived to sustain the development of complex life.
Putting plausible numerical estimates into the Rare Earth equation (not done in the book) suggests that there are only a few planets with complex life per galaxy.
The conclusion of WandB, which I have only been able to sketch here, is that Earth is a rare place where many random factors have conspired to create a nearly ideal site for the evolution of complex life.

 The Book 'Rare Earth' Punctures Alien Assumptions - UFO Evidence
In Rare Earth: Why Complex Life is Uncommon in the Universe, geologist Peter D. Ward and astronomer Donald Brownlee present a thoughtful, well-argued case that animals (let alone astronomers) are rare and perhaps limited to Earth.
The authors seem to believe that intelligent life probably exists somewhere else in the galaxy, but their line of reasoning also leaves open the possibility that Earth is, as they put it, "extraordinarily rare." Interestingly, if the authors are wrong about bacterial life, this would strengthen their main argument.
Less convincing, however, is their assertion that the "Rare Earth Hypothesis" gives added reason for protecting endangered animal species on Earth.

It would be remiss to not mention that Rod Stewart had a huge album with the same title in 1977, indicating the "new" Rare Earth was watching the hitmakers and restructuring the music.
Though far and away the best of the three Prodigal discs (even though Rare Earth's final hit would be on the Band Together LP), the move to funk is too blatant, and feels too calculated.
The problem is, again, that Rare Earth's success was always in transferring one genre to another.
