人工選擇

人工選擇(英語:Artificial selection,又譯人擇)是指針對特定性狀進行育種,使這些性狀的表現逐漸強化,而人們不需要的性狀則可能逐漸消匿的過程。最早對此進行定義的科學家為查爾斯·達爾文,他以發生在馴養動物的人擇過程來闡述演化過程中的自然選擇(或稱天擇)機制。

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
