I scored 12/15 = 60%

(And I consider myself pretty well informed about natural selection!)

How did you do?

[mike_c]

1. 15/15-- 100 percent....

But I live and breathe this stuff.

[BurtWorm]

2. I hope others will report on their results.

I don't want to be the only 60%er. :scared:

Actually, considering I don't live and breathe this stuff, I'm not too unhappy with my score.

[IChing]

3. 13/15 but I'm a B student

[Paulie]

4. I also got a 60

The ones quoting Darwin got me (none of the above?).

[BurtWorm]

6. I winged it on blending inheritance.

I'd never heard of it until today. :blush:

[seemunkee]

5. 67%

Not that great.

[Frank Cannon]

13. That's what I got

Guess I'm not as smart as I thought I was.

[TZ]

8. Oh I got the same score...

but its been about 16 years since I really studied this stuff. And I can console myself that the ones I got wrong, I strongly considered the right answer too.

[tandot]

9. Don't worry. I thought I knew more about it, but only scored 10/15

I passed with 60%.

[BurtWorm]

10. Wait a minute...

If you had 10 of 15 and I had 12 of 15, how did we both get 60%?

I must have misread my grade.

[TahitiNut]

26. You did. The pop-up said that 60% was passing ... and then showed your score.

Clearly, 12/15 is 80%, not 60% ... and 10/15 is 67%, not 60%.

If it were an arithemtic test, it seems a few wouldn't have passed. :evilgrin:

[BurtWorm]

27. The problem was reading comprehension, then.

And I was an English major! :eyes:

[tandot]

On the top it said 60% - passing grade or something like that.

Further down it showed the exact score. Mine said 67% percent, which now seems odd since you scored higher than me.

on edit: the score on top just shows what percentage is needed to pass (60%). Further down it shows your score. I re-did the test and got 11/15 this time, which was 73%

:hi:

[EstimatedProphet]

12. 11/15-I hoped to do better but I've been out of school for a decade now

Guess I need a refresher.

[TahitiNut]

14. Ditto ... but I don't live and breath the stuff.

:shrug: Thanks to Gregor Mendel. :silly:

[Squatch]

7. 100%

[phantom power]

11. 13/15: 87%

I would quibble at the wording of 11. The whole point of selection is that populations can't "grow infinitely." But I get what they were trying to say. I'm surprised that Darwin thought blending inheritance was plausible.

[IChing]

17. I missed that one also and agree n/.t

[HiFructosePronSyrup]

20. I'm not surprised at all.

It basically boils down to inheriting traits from your parents. Mendel refined it unknown to Darwin, but it would have been obvious to 19th century biologists.

[phantom power]

28. The thing about blending is, it has no mechanism for producing variation.

In fact, it damps out any existing variation quite rapidly. I can only assume Darwin considered it as one mechanism, where some other mechanism was responsible for variation.

I guess I still shouldn't be surprised. Lots of things seem "obvious" to somebody like me born after the discovery of DNA, and 150 years of population genetics, that wouldn't have been at all obvious to a biologist living in Darwin's day.

[RebelOne]

15. I am totally clueless about Natural Selection,

but I scored 60%. Much of it was guesswork.

[tjwash]

16. 12 of 15 is 80 percent. The test just says that 60% is a passing grade.

Do I win something for noticing?

[IChing]

23. Yeah, they can't do math- 9 out of 15 is 60%

[BurtWorm]

25. If that had been a math test, I very likely would have done much worse.

:patriot:

[RebelOne]

31. If it had been a math test, I would have flunked. n/t

[Arkansas Granny]

18. I scored 13/15 which surprised me since I've been out of school

for over 40 years now. My biology teacher would have been proud.

[tmlanders]

19. I got 67% correct nt

[lapfog_1]

21. 13/15, but I never pick "none of the above" though the

other answers seemed to not be quite right... I picked one anyway. It's also been 25 years since I took a college course on the subject "Theory of adaptation in natural and artificial systems" (which was how to create software to mimic evolution.)

[youthere]

22. 13/15 87%

[fasttense]

24. I failed. I only got 57% but that blended inheritance

threw me. I thought Darwin was against it but he was more accepting of the theory than I thought.

[malaise]

29. 11/15

73%. This is bad.

[Jim Warren]

30. 12/15 is 80%

You did better than you thought, maybe?

My score: 11/15=73%

[BurtWorm]

33. I did.

Phew! (Glad it wasn't a math test.)

[Bunny]

32. 13/15, which is better than I expected to do.

Go me! :woohoo:

:hi: BurtWorm!

[BurtWorm]

34. Congrats, Bunny!

:applause:

:hi:

[unpossibles]

35. 12/15 is 80%

I got 11 right - 73%
