yet conclusively been shown how the features in the meteorite were formed, similar features have been recreated in the lab without biological inputs by a team led by D.C. Golden. McKay says these results were obtained using unrealistically pure raw materials as a starting point, and "will not explain many of the features described by us in ALH84001." According to McKay, a plausible inorganic model "must explain simultaneously all of the properties that we and others have suggested as possible biogenic properties of this meteorite." The rest of the scientific community disagreed with McKay.

513:. RNA organisms, which are expected to have lived on Earth during the time period when ALH84001 was ejected from Mars, may also have been as small or smaller than these structures, as modern RNA viruses and viroids are often as little as a few dozen nanometers. Some of the structures are even larger, 1â2 microns in diameter. The smallest structures are too small to contain all the systems required by modern life.

Martian meteorites does not resemble the microscopic shapes in ALH84001. In particular, the shapes within ALH84001 look intergrown or embedded in the indigenous material, while likely contamination does not. While it has not
