The basic unit of the Family Trees logo is an ancient symbol representing a human as a vertical line with outstretched arms. This symbol is one of the oldest know representations of 'man'.

Trees are then also represented by the same symbol, drawing parallels between the 2 living species. When placed in a group together, the connection between humans and trees - a core mission of Family Trees - is highlighted.

Finally, when rotated to form a globe, the connected symbols become a universal gesture of kinship and solidarity encircling the world.
