Dorion Sagan (2010)In hmolscience, Dorion Sagan (1959-) is an American science writer noted for being a popular scientific editorial co-author for a number of publications, 1995 to present, tending to surround the topic of the origin of life, thermodynamics, evolution, and purpose.

In 1995, Sagan co-authored What is Life with his mother Lynn Margulis, wherein the expound on endosymbiotic theory to explain the origin of life.

In 1997, Sagan and Margulis published What is Sex, and more simplified version of the former, on bacterial "sex", so to say.

In 2005, Sagan, together with American ecological thermodynamicist Eric Schneider, penned Into the Cool: Energy Flow, Thermodynamics, and Life, in which they outline a degrade-the-gradient thermodynamic meaning of life. [2]

In 2013, Sagan, in his Cosmic Apprentice, attempted to tackle evolution and entropy. [3]

Sagan, the son of Carl Sagan and Lynn Margulis, seems to be mostly self-educated in the science. Sagan, in this end, has authored or co-authored numerous articles and 23 books translated into eleven languages.

It seems that in the book "Into the Cool - Energy Flow, Thermodynamics, and Life" ideas and drawings from my 1992 paper "Life on Earth - flow of Energy and Entropy" are used without my permission or due credit.
