AuxLang Project 12a: Vocabulary (Part One)
How many words?
How many words does Okeslan need? For the sake of simplicity, I'd say as few as it can.
Ogden and Richards' Basic English famously cut down the general-purpose English vocabulary to 850 words, but as Mark Rosenfelder points out, they had to use idioms whose meaning cannot be deduced from the components (e.g. for "succeed", even though doesn't mean "fail").
The Swadesh List is a compilation of basic words that are found in all languages, and that are commonly used to measure the degree of relation of multiple languages. In its final formulation (1971), the Swadesh List has 100 words, including simple concepts ("all", "not", "this", "big"), organisms ("dog", "fish", "tree"), bodyparts ("head", "eye", "bone", "hand", "egg"), actions ("eat", "sleep", "know"), elements of nature ("water", "sand", "mountain") and qualities ("cold", "good", "round").

, "name, designation, to call/name"* (chiefly from Indo-European , also found in Thai and Malayalam, and from Japanese , but also from Turkish , Russian and Korean )
, "life, alive, living, to live" (compare Hindi and Italian , with elements of Mandarin and Arabic )
, "death, dead, to die, to kill" (compare Indo-Aryan , Arabic , Russian , Cantonese ) and Turkish )
, "word" (mostly from the Arabic - and thus Persian and Turkish - , Thai and Bengali/Malayalam/Javanese )
, "touch, contact, to touch" (see Mandarin , Hindi , Telugu , Swahili )
, "God, deity, divine" (an ungodly mixture of Sanskrit , Arabic , Vietnamese and Turkic )
, "will, desire, to want" (from German , Polish [now that's a word!], Cantonese , Bengali ); though maybe it could be shortened to , to make it more comfortable as a verb modifier.
, "clean, wash" (from Turkish , Persian , Vietnamese )
, taken straight from Vietnamese, is our new verb modifier for "should" or "ought".

SftD: Oromian Reef
A portion of reef in the shallow waters of the Oromian Sea, from Settlers from the Deep. A variety of sessile gastropods descended by cone snails can be seen, including many parasites of the larger species, as well as filter-feeding tube worms. A sparkfish hovers above, searching for gills and tentacles to bite off. The tube worm in the front is a predator, which exploits resemblance to innocuous relatives to wrangle a fish or crab in its tentacles.
My submission for COM 73 on the Speculative Evolution forum.

The leucrota, or leucocrota, or crocotta, a creature from Medieval bestiaries with an extremely wide mouth and the ability to replicate human voice, reconstructed as an Andrewsarchus-like carnivorous basal ungulate.
SftD: Predators of the Thunderwhale
Parasites and predators of filter-feeders, from the oceans of Settlers of the Deep. Bdellocephalus and Polybelon are parasites descended from electric catfish, like their enormous host: one sucks fluids through a sucker mouth, while the other pierces its skin with rigid stilettoes. Spheconectes is a swimming pack hunter descended from cone snails.
SftD: Bountiful Sea
Inhabitants of the open oceans from Settlers from the Deep. Aspidurus examinans is a minute crustacean derived from crabs that retain a larva-like form all their life, and form vast swarms just below the sea surface. Phagonauta exulans is a catfish descendant that wanders the ocean catching the wind in an oversized dorsal fin, trawling sticky barbels in the water to catch preys. Pogonocetus tiresias, another catfish descendant, is a huge, blind filterfeeder that locates bugfish swarms with an array of chemical and electric sensors.
Logarithmic Timeline
Here's my latest project - about three months in the making, it's a timeline of all history, from the distant, cosmic events like the formation of the Milky Way and the Solar System, to the news that we all remember from the last few years. The scale changes according to a logarithmic function, so it accelerates as it goes deeper into the past; more detailed explanations are included in the picture itself. In many cases, the choice of events to include was largely arbitrary.

when will you be going back to work on history of life?
Concavenator Featured By Owner Oct 1, 2016
Alas, I don't know. I have several different projects I'm currently working on, one of them frustratingly close to completion, and I'd like to finish at least a couple of them before going back to something as demanding as the History of Life. That said, I want to go back to it, sooner or later, and I promise someday I will.
