Who’s Out There–Weirdos?3 min read

A review of “Weird Life: The Search for Life That Is Very, Very Different from Our Own” by David Toomey, New York, W.W.Norton, 2013. by Cary Neeper 

Author David Toomey treats us to a detailed exploration of what kind of life is weird and why, both chemically and physically. He reminds us that eyes come in all varieties and how remarkable it is that our eyes are so similar to those of octopuses. Convergent evolution can operate at the cellular level since it is good at finding and repeating what works well–a hopeful hint that life may occur just about anywhere with a reasonable climate.

Weird Life: The Search for Life That Is Very, Very Different from Our Own
by David Toomey (Goodreads Author)

Toomey considers Mars and what any life would need to do to survive there now. The flooding of four billion years ago and Mar’s atmosphere now are both reviewed with possible life-needs considered. The acidity and salinity of the ancient Martian lake Yellowknife Bay was apparently very low 3.5 billion years ago. Also, the mild acidity and elevated salinity of the Robert Sharp crater suggest that both may have been “hospitable to life.” (See eos.org/research-spotlights)

Also noted by author Sarah Stanley (Source: Journal of Geohysical Research:Planets) These craters on Mars also contained akaganeite, which (on Earth) forms in “acidic, saline wet environments,” hence the hope that they were wet at some stage. The pH of Yellowknife Bay was probably between 1.6 and 8. Basaltic minerals or exposure to iron sulfides was
feasible in the Robert Sharp crater.

In his book “Weird Life,” Toomey asks if viruses are alive. Any definition of life, he says, is “likely to be provisional.” He decides that liquid is probably necessary for “what life needs.” Proteins seem to be critical, or at least handy. Even weird life would use molecules similar to the familiar ones in common Earth biology since they work so well, especially if made of carbon.

Silicon has problems doing life–high reactivity with water and oxygen, inability to form double or triple bonds like carbon, and macromolecules too repetitive to be creative. On Earth silicon is “locked into rocks” since it is too reactive with oxygen to invent life forms.

The author explores cosmological options and the multiverse idea, as well as the idea of extraterrestrial intelligence, before noting that life elsewhere is most likely not to be weird, but to resemble Earth’s. He notes that the interests of theoretical physicists, astronomers and biologists are likely to differ in emphasis. In any case, though bio-signatures in alien life may differ, they “could be detected…readily.”

Cary Neeper is an avid student of complexity theory, sustainability, steady-state economics, and the impact of cosmology on issues of science and religion. She grew up in the foothills of Hayward, California, where she helped rack dried fruit on her father’s 40-acre apricot ranch. After studying zoology/chemistry and religion at Pomona College and medical microbiology at the University of Wisconsin, she moved with her husband to northern New Mexico, where they raised their family. The Neepers still live in the Southwest with a friendly menagerie of dogs, fish, chickens, geese, ducks and a turkey called Little Bear. Cary plays string bass with local folk, symphony and jazz groups and tennis with local retired physicists. She paints landscapes in acrylics, including the cover art for her first Penscript title, The Webs of Varok. Cary's first novel and Webs of Varok prequel A Place Beyond Man was originally published in 1975 by Charles Scribner’s Sons, Dell, and Millington, London. Cary re-released A Place Beyond Man as an Author’s Guild Backinprint edition, now available from online booksellers. Its themes of sustainability and interspecies cooperation have now grown into new adventures for its human, elll and varok family as they travel the alternate 21st century Solar System in the five-volume Archives of Varok, coming from Penscript Publishing House in 2012–2014. Cary’s other works include two musical science fiction comedies “U.F.F.D.A.!” and “Petra and the Jay,” as well as newspaper and magazine articles, essays, short stories, and book reviews for The Christian Science Monitor.
