family tree

Investigative genetic genealogy is a tool in which modern investigators build family trees using crime-scene DNA that has been entered into databases.

With the study also comes a new reconstruction of the evolutionary family tree for pterosaurs.

Genealogist Bill Lawson, who has traced the family tree of Mary Anne MacLeod back to the early 19th Century, says her father Malcolm ran a post office and small shop in his later years.

Then, in 2022, she received a notification - a full sibling had joined her family tree.

"We have a family tree that goes back to the great fire in London that was hand-done by my grandmother," he explained.
