Alfred Russel Wallace 
Is Mars Habitable? A Critical Examination Of Professor Percival Lowell’S Book 

Percival Lowell's theories that intelligent life exists or formerly lived on Mars and constructed the canals are subject to a scientific assessment in the book "Is Mars Habitable? " Lowell was an amateur astronomer, but Wallace is a scientist by profession and applies science to Mars with a little more discipline. An article about the likelihood of biological life existing on Mars is titled "Is Mars Habitable." The Welsh town of Llanbadoc is where Alfred Russell Wallace was born on January 8, 1823. With the goal of demonstrating that the abundance of novel and fascinating information in Professor Percival Lowell's book, Mars and its Canals, did not invalidate the conclusion he had reached in 1902 and stated in my book on Man's Place in the Universe that Mars was not habitable, this small volume was originally intended to be a review of that work. However, the more thorough presentation of the opposing viewpoint in the volume under consideration necessitated a more thorough analysis of the different physical issues involved, thus the author decided to take on the task given the topic's high level of popular and scholarly interest.
