... on these expanded membranes [butterfly wings] Nature writes, as on a tablet, the story of the modifications of species, so truly do all changes of the organisation register themselves thereon. Moreover, the same colour-patterns of the wings generally show, with great regularity, the degrees of blood-relationship of the species. As the laws of nature must be the same for all beings, the conclusions furnished by this group of insects must be applicable to the whole world.
Interpretation
The structure and colors of butterfly wings reflect the evolutionary history and relationships among species, illustrating the universal laws of nature.
Henry Walter Bates highlights how butterfly wings serve as a testament to the evolutionary modifications of species, acting as a record of their lineage and relationships. The intricate patterns and structures not only showcase the unique adaptations of each species but also suggest that the same natural laws govern all living beings, allowing for broader implications about evolution and interconnectivity in nature.
In practice
In a presentation about biodiversity, one might use this quote to illustrate the interconnectedness of species.
Men need to know the elemental challenges that sea and mountains present. They need to know what it is to be alive and to survive when great storms come. They need to unlock the secrets of streams, lakes, and canyons and to find how these treasures are veritable storehouses of inspiration. They must experience the sense of mastery of adversity. They must find a peak or a ridge that they can reach under their own power alone.
The evergreen! How beautiful, how welcome, how wonderful the evergreen! When one thinks of it, how astonishing a variety of nature! In some countries we know that the tree that sheds its leaf is the variety, but that does not make it less amazing, that the same soil and the same sun should nurture plants differing in the first rule and law of their existence.
AND what is so rare as a day in June? Then, if ever, come perfect days; Then Heaven tries earth if it be in tune, And over it softly her warm ear lays; Whether we look, or whether we listen, We hear life murmur, or see it glisten.
All our environmental problems become easier to solve with fewer people and harder - and ultimately impossible to solve - with ever more people.
Oh, a dainty plant is the ivy green, That creepeth o'er ruins old! Of right choice food are his meals, I ween, In his cell so lone and cold. Creeping where no life is seen, A rare old plant is the ivy green.
Why is it so easy to save the banks - but so hard to save the biosphere?
