Peanut

TL;DR

50% oil by weight—9 cal/g vs carbohydrates' 4 cal/g. Dense capital (equity) vs liquid capital (debt) in seed form.

Peas store carbohydrates. Peanuts store oil. Both strategies work for germination, but the tradeoffs reveal fundamental choices about capital structure that appear throughout business.

A peanut is 50% oil by weight—one of the most energy-dense storage strategies in the plant kingdom. Oil contains 9 calories per gram versus carbohydrates' 4 calories per gram. The peanut packs more than twice the energy density into the same seed mass. This isn't extravagance; it's engineering for specific conditions.

The peanut (Arachis hypogaea) evolved in South American soils where it developed an unusual reproductive strategy: after pollination, the flower stalk elongates and buries the developing pod underground. This geocarpy—fruit development in soil—means the seed germinates in a dark, competitive root zone where rapid establishment matters. Oil reserves provide the concentrated energy burst needed to push through soil and establish before competitors.

The business parallel is capital structure optimization. Some startups raise equity (dense, expensive capital) while others bootstrap or use debt (less dense, more dilutive in the long run). Neither is inherently superior—the right choice depends on competitive dynamics and establishment speed. Biotech startups typically require equity financing because the capital intensity and timeline demand concentrated resources. SaaS companies can often bootstrap because they reach revenue faster.

George Washington Carver's peanut research at Tuskegee Institute produced over 300 derivative products—from peanut butter to ink to synthetic rubber. This wasn't random exploration; it was recognition that oil-rich seeds are chemical feedstocks. The peanut's storage strategy created optionality: the same reserves that fuel germination can be redirected into industrial applications. Equity capital works similarly—it's fungible in ways that debt is not.

Peanut oil also demonstrates storage longevity. Fats oxidize more slowly than carbohydrates under proper conditions, giving oil-storing seeds longer viability. Similarly, equity capital typically has longer runway than debt—no monthly payments, no covenants triggered by performance metrics. The tradeoff is ownership dilution.

Different environments favor different strategies. Peas (carbohydrate-storing) germinate faster initially because carbohydrates convert to usable energy more quickly than oils. But peanuts win in resource-limited underground competition where total energy matters more than initial speed. Similarly, bootstrapped companies may launch faster, but venture-backed competitors often win in markets where sustained investment creates lasting advantages.

The peanut's lesson: the same germination problem has multiple viable solutions, and the right storage strategy depends on competitive conditions, establishment timeline, and the tradeoffs you're willing to accept. For the carbohydrate approach, see how peas activate through imbibition.
