Adam was a chemist on Kelowna. He received a non lethal but still harmful dose of radiation in the accident that killed Dr. Jackson. Like Jonas he hated how the government was covering up the truth. He wasn't sure about leaving home to live on Earth like Jonas but when approached about Phoenix he readily agreed. A Tok'ra already on Phoenix was in need of a new host and Adam's natural curiosity as well as his desire to heal the damage caused by his radiation poisoning made him agree to blend with Gemy'ni. Gemy'ni is a highly respected archaeologist within the Tok'ra ranks and was thankful to find a volunteer as his new host.
