    History Revision
AI Thread Summary
The discussion revolves around the confusion regarding the revision history of sequences in the NCBI nucleotide database. Users observe that multiple entries in the revision history display the same version number despite having different update dates. This raises questions about whether these updates pertain to the sequence itself or merely to the annotations. Accessing the revision history is straightforward; users can find it by selecting the option in the display settings after viewing an entry. The conversation highlights the need for clarification on the nature of these revisions, emphasizing the distinction between sequence updates and annotation changes.

Okay so I'm using ncbi and when using the nucleotide database, when I access the revision history of a result of any query, I get a lot of sequences. Surprisingly they all are of the same version. Why? If each is different shouldn't they have different version numbers? They all have different update dates yet all are the same thing (same version). Can someone explain them to me?

Attached is a screenshot explaining what I mean.

How do you get to the revision history? I've never seen that. And couldn't the revisions be updates on the annotation and not on the sequence itself?
 
Accessing revision history is simple. After accessing an entry, you go to the top left side of the page and in display settings you select revision history and press ok.

And maybe you're right with regards to revisions being updates on the annotations. It does make sense. But I need to know definitely (no offence).

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
