# On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event

Date: 1858

## The fact

On 1 July 1858 [Darwin](/people/charles-darwin)'s extracts and Wallace's paper were read jointly at the Linnean Society. The instrument is that dated co-priority reading, not the November 1859 book as a duplicate. Charles Darwin's documented role is: Lyell and Hooker arranged the reading. Wallace's Ternate letter is his. Darwin's extracts are his. Neither man was in the room as later told.

## Context

Wallace is the named co-author of the idea's first public pairing. Lyell and Hooker arranged. Sharing them is required. The setting of On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event is the public file around 1858-07-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver edu-[digital-learning-access](/drivers/edu-digital-learning-access) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

Shared responsibility is part of On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event. Naming Charles Darwin does not delete co-authors, institutions, or later transmitters. The lag from 1858-07-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

## Significance

Improving path from On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event on 1858-07-01. A joint public reading of natural selection is an education path of high weight. Wallace is named, not erased. The welfare reading on this path is improving.

## What is established and what is not

Established: a sourced public record of On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event under 1858-07-01 for Charles Darwin. Established: a sourced public record of On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event under 1858-07-01.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

If a number is not in the two records named above, it is not supplied here.

Confidence is stated on the impact path, not hidden in adjectives. Do not store Origin 1859 as this July meeting. Two instruments. Mixed effects of On 1 July 1858 Darwin's and Wallace's papers are read jointly at the Linnean Society as a dated co-priority event are separate paths.

The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.
