research on Galaxias maculatus proved that its freshwater distribution around the Southern Hemisphere was due to dispersal through the sea of salt-tolerant juveniles. He has also worked on other Chilean galaxiids.

Charles Darwin Fascinated as a child by the adventures of the HMS Beagle and the naturalist William Beebe, Berra has written several books on Charles Darwin, Darwin's family and in 1977, Beebe. Charles Darwin: The Concise Story of an Extraordinary Man was published in 2009, timed for the 200th anniversary of Darwin's birth in 1809. Berra became interested in the children of Darwin and his wife Emma Wedgwood. The children had often been mentioned in other books, but little had been written about their lives, Berra researched the ten children and published Darwin and His Children: His Other Legacy in 2013. Darwin and his wife were first cousins, which interested Berra on how this might have affected the family genetics. Their consanguine marriage possibly affected the children with "reduced fertility" compared with similar families of their class during that time. Seven children lived to adult-hood, only three of those had children. Darwin himself suffered from ill-health, "severe digestive problems and a skin disease that made shaving so painful that he grew his distinctive beard." Berra asked researchers in Spain who had used computer modeling to understand the genetics of the Habsburg family tree to look into the genetics of the Darwin family. The result was that there was an increased risk of low infertility and bacterial infections which at least two of Darwin's children died of. In 2016 the Washington Post contacted Berra to weigh in on
