NEW YORK (AP) — A letter by Charles Darwin on the sex life of barnacles and a still-working vintage Apple computer — one of only 50 made in Steve Jobs’ garage in 1976 — are among the unique pieces of science history up for auction this month.

Buyers at the Oct. 22 event at Bonhams will need deep pockets. The Steve Wozniak-designed Apple 1 computer is estimated to bring $300,000 to $500,000. One sold at auction last year for $671,000.
