Christmas Cards

Our festive cards are folded to A6 and come in packs of 10, including envelopes. The cards are blank inside, and have some information about the design and the BHA on the reverse. They’re printed on recycled paper.

2014 Card: Tree of Life

Our 2014 card is a festive representation of Charles Darwin’s Tree of Life – his first sketch of the idea that all species are related, and evolved from a common ancestor.

The tips of the branches represent species that are alive today, and as you travel from the star to his hat you pass every species that has ever existed (plus the Galápagos Finch, which played an important role in the inception of Darwin’s theory of evolution by natural selection.)

Pine cones naturally grow in Fibonacci spirals – a form of the ‘golden ratio’ that pervades nature, mathematics and art. We think they’re an appropriately festive and fascinating symbol to help celebrate the holiday season and the turning of the year.
