State consistently whether extinction is or isn't defined to include pseudoextinction

Is pseudoextinction a special case of extinction, or are they mutually-exclusive in a given case?

The pseudoextinction section suggests the former as it begins with:

Descendants may or may not exist for extinct species.

Which implies that a pseudoextinct species (which by definition must have existing descendants) can indeed be considered extinct.

But, inconsistent with that, there are phrases elsewhere that appear to assume that a species can be pseudoextinct and not be considered extinct:

"pseudoextinct, rather than extinct"
"Pinpointing the extinction (or pseudoextinction)"

So which is it: is a pseudoextinct species also considered extinct, or not, or is the answer controversial, or, worse yet, context-dependent? The word pseudoextinct can be read literally (or at least etymologically) as "falsely extinct", so how can it be that a "falsely extinct" species is also (truly) extinct? :-) But are there any good citations on one or both sides of this question?

Needs a section

Hi, this is my first time looking at this article. I noticed that humans are mentioned under the "causes" section although it seems somewhat unorganized. I think there should be a separate section devoted to human activities such as poaching. Poaching (and/or human activities) should have its own section I think. --Turn685 (talk) 09:45, 25 January 2014 (UTC)

The age of the Earth is about 4.54 billion years.[1][2][3] The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,[4][5][6] during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[7][8][9] Earlier physical evidences of life include graphite, a biogenic substance, in 3.7 billion-year-old metasedimentary rocks discovered in southwestern Greenland,[10] as well as, "remains of biotic life" found in 4.1 billion-year-old rocks in Western Australia.[11] [12] According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe."[11]

History of Scientific Understanding Needs Update

Hi, I'd like to flesh out the section on History of Scientific Understanding. This is my first time editing wikipedia, so please let me know if you have feedback. --limulus120 22:19, 23 April 2017 (UTC) — Preceding unsigned comment added by Clara.roeder (talk • contribs)

I just completely re-did the History of Scientific Understanding section, with more citations and a more in-depth take on pre-extinction theories --limulus120 17:46, 5 May 2017 (UTC)

I believe that extinction has already occurred, by way of 50 years of human always ongoing evolution. I do not believe it requires genocide. That is, homo sapiens "wise ones" to what is outside of domiciles, now includes clothing, cars, and smartphones, might be renamed in latin terms. The age of paranoia, beginning in 1995, is over. Less disinformation please. We don't use fake names. — Preceding unsigned comment added by CheathamPatrick (talk • contribs) 12:30, 5 February 2018 (UTC)

All of the extinctions by 2100

It says that up to half of plant and animal species that live today could die out by 2100. Up to half of plant and animal species that live in what year? We don't want 2099 to come and it says they could be gone by 2100 or worse, 2101 to come and it says 2100.
