OFFICIAL7 Why does the professor talk about speciation?

[00:00.00]Narrator: Listen to a conversation between a student and a professor.
[00:05.51]MALE STUDENT: Hi, Professor Mason. Do you have a minute?
[00:07.54]FEMALE PROFESSOR: Yes, of course, Eric. [00:09.09]I think there was something I wanted to talk to you about, too.
[00:12.59]MALE STUDENT: Probably my late essay.
[00:14.16]FEMALE PROFESSOR: Ah, that must have been it. [00:15.83]I thought maybe I'd lost it…
[00:17.66]MALE STUDENT: No, I'm sorry. [00:18.86]Actually, it was my computer that lost it, the first draft of it, [00:21.87]and... Well anyway, I finally put it in your mailbox yesterday.
[00:25.08]FEMALE PROFESSOR: Oh, and I haven’t checked the mailbox yet today. [00:27.59]Well, I’m glad it's there... [00:29.10]I’ll read it this weekend.
[00:30.51]MALE STUDENT: Well, sorry again. [00:32.18]Say, I can send it to you by e-mail too, if you like.
[00:35.19]FEMALE PROFESSOR: Great, I'll be interested to see how it all came out.
[00:38.32]MALE STUDENT: Right. Now, uh,  I just overheard some graduate students talking...something about a party for Dean Adams?
[00:44.70]FEMALE PROFESSOR: Retirement party, yes… all students are invited. [00:48.04]Wasn't there a notice on the anthropology department's bulletin board?
[00:51.23]MALE STUDENT: Uh, I don't know. [00:52.84]But... I wanted to offer to help out with it. [00:55.42]You know, whatever you need. [00:56.69]Dean Adams, well, I took a few anthropology classes with her, and they were great. Inspiring. [01:02.04]And, well, I just wanted to pitch in.
[01:03.45]FEMALE PROFESSOR: Oh, that's very thoughtful of you, Eric, but it'll be pretty low-key. Nothing flashy. [01:08.68]That's not her style.
[01:09.88]MALE STUDENT: So there's nothing?
[01:11.03]FEMALE PROFESSOR: No, we'll have coffee and cookies, … maybe a cake. [01:14.32]But actually, a couple of the administrative assistants are working on that. [01:17.77]You could ask them, but I think they've got it covered.
[01:20.61]MALE STUDENT: OK.
[01:21.77]FEMALE PROFESSOR: Actually … no, never mind…
[01:25.50]MALE STUDENT: What is it?
[01:26.26]FEMALE PROFESSOR: Well… It's nothing to do with the party, and I'm sure there are more exciting ways you could spend your time, [01:31.87]but we do need some help with something.  [01:33.91]We’re compiling a database of articles the anthropology faculty has published. [01:38.68]There's not much glory in it, but we're looking for someone with some knowledge of anthropology who can enter the articles…[01:45.56]I hesitate to mention it, [01:48.04]but I don't suppose this is something you would...   
[01:50.65]MALE STUDENT: No, that sounds kinda cool. [01:52.90]I'd like to see what they're writing about.
[01:54.91]FEMALE PROFESSOR: Wonderful... [01:55.97]and there are also some unpublished studies. [01:58.75]Did you know Dean Adams did a lot of field research in Indonesia? [02:02.77]Most of it hasn't been published yet.
[02:04.97]MALE STUDENT: No, like what?
[02:06.33]FEMALE PROFESSOR: Well, she's really versatile. [02:08.31]She just spent several months studying social interactions in Indonesia, and she's been influential in ethnology. [02:14.53]Oh, and she's also done work in South America.[02:17.14]That's closer to biology—especially with speciation.
[02:20.64]MALE STUDENT: Uh, not to seem uninformed…
[02:23.13]FEMALE PROFESSOR: Well, how species form… [02:25.24]you know, how two distinct species form from one—[02:29.11]like when populations of the same species are isolated from each other and then develop in two different directions, and end up as two distinct species.
[02:37.94]MALE STUDENT: Interesting.
[02:38.85]FEMALE PROFESSOR: Yes, and while she was there in South America, she collected a lot of linguistic information, and songs…really fascinating.
[02:46.37]MALE STUDENT: Well, I hate to see her leave.
[02:48.41]FEMALE PROFESSOR: Don’t worry. [02:49.30]She'll still be around. [02:50.42]She's got lots of projects that she's still in the middle of.
