Made up of cellulose, hemicellulose, and lignin polymers, these parts of the plant evolved to protect and preserve the integrity of plant structures, so they are difficult to break down.
Ostriches and penguins, for example, evolved from flying ancestors, and preserve their flight-adapted feathers.
As the circus evolved over the course of the 20th century, many worked to teach and preserve the fundamentals of the art form.

It may eventually be possible to use engineered consortia like this one to determine how relationships between interacting, co-evolving populations are enhanced and preserved by particular physical structures.
The purple-pink-tinged Precambrian sandstone comprising the bulk of Liathach was laid down as long ago as 1,000m years, before multicellular organisms had evolved, and has preserved only plankton-like nannofossils.
Although many varied forms of life evolved and were preserved extensively as fossil remains in Cambrian sedimentary rocks, detailed mapping and examination of Precambrian rocks on most continents have revealed that additional primitive life-forms existed approximately 3.5 billion years ago.
These are reminders that our values have an ambiguous history, and they need to evolve to preserve the best of the past while enabling better from the future.
As the art world evolves, new forums for presenting and preserving collections emerge, id.
Efficient cell cycle checkpoint signalling and DNA repair pathways have therefore evolved to preserve cell viability (Jackson and Bartek, 2009).
