Question

12. For a behavior to evolve under the influence of natural selection, that behavior must have been influenced by what?

Answer 1

@ShadowLegendX

Answer 2

@mrdoldum Is here! Then why to worry!

Answer 3

lol truu i didn't know

Answer 4

so are u @mrdoldum gonna help me

Answer 5

i be right back but still comment on this k

Answer 6

Ug, another poorly worded question. I am not 100% sure what the question wants. Taken literally, the question answers itself. A behavior must be under selection in order to undergo any evolution. Do you have anymore context? Can you tell me about what you discussed in class?

Answer 7

What is the behavior influenced by? is the question basically

Answer 8

@mrdoldum

Answer 9

Well, see that is the thing. We call that selection. There can be positive selection and negative selection. So, for a behavior to evolve it would depend on the behavior on whether it evolved under positive or negative selection.

Answer 10

ok thanx but hold on k

Answer 11

Sure.

Answer 12

ok well um... i get it i think

Answer 13

its probably negative

Answer 14

@Phebe It could also be discussion innate vs. learned behaviors. In one case the selection would be working directly on a gene or set of genes, while learned behaviors would result in a less specific set of changes in the organisms genome.

Answer 15

ok so it deals with genetics right

Answer 16

Well, evolution has to work on genes or it is not occurring*. Even in learned behaviors there must be some sort of genetic basis if you dig deep enough into it. However, a learned behavior may not need a specific allele or set of alleles. It could be learned by a very broad range of alleles, while at the extreme, a instinctive behavior might require a specific allele.

Answer 17

ok thank you very muchhh XDXD

Answer 18

Yeah! Thats @mrdoldum ! Thank you sir! Even I had a doubt in that!

Answer 19

lol ikr XD

Answer 20

*some things can be past on from parent to offspring that affect the organism but not the DNA sequences. We refer to such things as epigenetics. This is a rather advanced topic and probably more than you want to hear unless you are in college/university.

Answer 21

ok thank you @mrdoldum

Answer 22

What is

A) Influenced by genes.
B) Neither adaptive nor harmful.
C) Acquired through learning.
D) Related to predator avoidance.

Answer 23

@murp101 make your own thread. Also, that question does not make any sense.

Answer 24

No, she/he is saying that those were the answer choices.

So which on of them is it?

@mrdoldum

Answer 25

@mrdoldum did you get the answer.... is a b c or d??? murp listed the answers.

Answer 26

@epicpanda I see what you mean by answers, he was doing a jeopardy thing. The thing is though, this question is crap. I don't need answers BTW, I am about 2 months from finishing a PhD in evolutionary molecular systematics of the Boletales (Fungi). I only get on here to help out students. I come from a family of teachers and I like teaching and helping others learn.

Answer 27

Yeah you're right @mrdoldum and that's fantastic! Best of luck to you my friend!
