SimBio Lab 2: Darwinian Snails
This lab is based on the work of biologist Robin Seeley (1986) and simulates the evolution of shell thickness in a population of flat periwinkle snails under predation by the European green crab. After a review of natural selection theory you will simulate an experiment with 2 snail populations.
Describe the three conditions necessary (variation, heritability, and differential survival) for evolution by natural selection.
Describe how a change in allele frequencies for a trait in a population constitutes evolution.
Understand that in the absence of natural selection, evolution can still occur through random chance changing the allele frequencies of a trait in a population.
Explain how genetic mutation creates a source of variation within a population.

Frequently asked questions
How soon can I get my paper done?
It depends with your deadline. If you need your paper completed in 3 hours, we will deliver it in that time. All you need to do is indicate your deadline in our custom order page here. Alternatively, if you are sending us your instructions via email, please be sure to indicate your deadline.
Will it be completely original? I don't want to be caught in a case of Academic Integrity Violation.
We are as paranoid as you are. Maybe even more! And we understand that the greatest sin you can commit in your academic journey is plagiarizing your academic work. To that end, we have made sure that we check and double-check our papers using high quality plagiarism detection tools such as SafeAssign and Turnitin before submitting the paper to you.
Who is my writer? Is he/she a native English Speaker?
All our writers are native English Speakers. That is not to say that ESL writers are not good, we just prefer hiring native writers because we want the very best people working on your paper. This might mean paying a little bit more for your paper as opposed to when you pay a foreign company whose writers are non-native English Speakers.
What if I need revisions? Will your charge additional for this?
Of course not! If you do happen to require a revision on your paper, our team will handle it for you free of charge. Matter of fact, we won’t rest till you are happy with your paper. So, ask for as many revisions as you need, it’s completely FREE!
Will you give me my money back if I don't like my paper?
We have very few instances where we delivered a paper that a client didn’t fall in love with. But if it so happens that you don’t like your paper for any reason whatsoever, we’ll refund your money back no questions asked.
I have more assignments after this, can you help me with those too?
Of course! And what’s even better is that we can reserve a writer permanently to work on your entire class. This comes in handy for projects which build up on each other and where you need just one writer, one writing style.
