I think that I shall never see

A thing so awesome as the Tree

That links us all in paths of genes

Down into depths of time unseen;

Whose many branches spreading wide

House wondrous creatures of the tide,

Ocean deep and mountain tall,

Darkened cave and waterfall.

Among the branches we may find

Creatures there of every kind,

From microbe small to redwood vast,

From fungus slow to cheetah fast.

As glaciers move, strikes asteroid

A branch may vanish in the void:

At Permian's end and Tertiary's door,

The Tree was shaken to its core.

The leaves that fall are trapped in time

Beneath cold sheets of sand and lime;

But new leaves sprout as mountains rise,

Breathing life anew 'neath future skies.

On one branch the leaves burst forth:

A jointed limb of firework growth.

With inordinate fondness for splitting lines,

Armored beetles formed myriad kinds.

Wandering there among the leaves,

In awe of variants Time conceived,

We ponder the shape of branching fates,

And elusive origins of their traits.

Three billion years the Tree has grown

From replicators' first seed sown

To branches rich with progeny:

The wonder of phylogeny.

日本語だと,鈴木理子詩集・系統樹』(1988年,国文社)がある.表題になっている長詩「系統樹」は,生き物の系統樹のルーツから末端までをたどる旅路を詩にした.ワタクシの『生物系統学』の「インテルメッツォ」で引用した.もう一冊は結城千賀子『歌集・系統樹』(2001年,角川書店[表現叢書第73篇]).その一句を『系統樹思考の世界』の末尾で引用したところ,著者ご自身から返信をいただいた.
