The olive tree was an iconic plant for most of the past Mediterranean civilizations, for which it had important economic value. Here we report the earliest use of fruits and wood from olive trees in Africa so far, around 100,000 years ago. These findings suggest the presence of olive trees on the Atlantic coast of Morocco during most of the last glacial period, and the use of olives by the early Homo sapiens for fuel management and most probably for consumption.

Exploitation and Management of the Olive Tree During Prehistoric Times in Mediterranean France and Spain
TLDR
Management of olive populations consistent with intentional and selective pruning practices may have been applied by man to rejuvenate olive trees in order to favour flowering and fruit production.
Olive oil production in Hellenistic Greece: the interpretation of charred olive remains from the site of Tria Platania, Macedonia, Greece (fourth–second century b.c.)
The Hellenistic farm site of Tria Platania in Macedonia, Greece, has revealed large quantities of charred olive remains, indicative of olive oil production from the fourth to the second century b.c.
Thirty thousand-year-old evidence of plant food processing
TLDR
Evidence of starch grains from various wild plants on the surfaces of grinding tools at the sites of Bilancino II, Kostenki 16–Uglyanka, and Pavlov VI suggest that vegetal food processing was a common practice, widespread across Europe from at least ~30,000 y ago.
Crop processing of Olea europaea L.: an experimental approach for the interpretation of archaeobotanical olive remains
TLDR
The remains of different processing stages are reasonably distinctive in the archaeobotanical record and assist in the identification of different types of olive remains, such as fragmented olive stones, the inner kernels, and fruit flesh.
Beginnings of Fruit Growing in the Old World
TLDR
It was concluded that introgression from the diversified wild gene pool facilitated the rapid buildup of variation in the domesticated crops and traced the various countermeasures that evolved to ensure fruit set.

Aim  This study intends to improve our understanding of historical biogeography of olive domestication in the Mediterranean Basin, particularly in the north‐western area.
Genetic diversity and gene flow between the wild olive (oleaster, Olea europaea L.) and the olive: several Plio‐Pleistocene refuge zones in the Mediterranean basin suggested by simple sequence repeats analysis
TLDR
To reconstruct the post‐glacial colonization history and establish a relationship between olive and oleaster populations in the Mediterranean basin, analyses were carried out on the genetic variation of chloroplast DNA (chlorotype) and at 12 unlinked simple sequence repeat (SSR) loci, sampling a total of 20 Oleaster groves.
