The Tree of Life is a science fiction story by Jennifer Rohn about a virologist sent back in time to study evolution. She  goes back with a stranger named Paul. She does not like Paul at first, but they get closer as the story progresses. He sporadically visits her while she is trying to develop a seed that could be beneficial to the planet and could survive. They have conversations about science that helps her gain respect for him. Her project fails in the end, but they become friends and he comforts her in her disappointment.

The science of cloning in this story is very accurate as Jennifer Robins PhD project was about cloning. Jennifer Robin has a clear understanding of evolution. She clearly outlines how evolution works in the afterword. The story very accurately displays what the earth was like at its inception.

Jennifer Rohn is a cell biologist at the University of London. She earned a PhD in Biology at Oberlin College. In 2011, Rohn won the inaugural Researcher Fortnight “Achiever of the Year” award. No doubt, Rohn is very qualified to write this story.
