Your task is to explore a primate hand features and explain how that primate hand feature enhance fitness.

I’m studying and need help with a Anatomy question to help me learn.

Webquest: Primate Hand Features

Introduction

The primary features that define primates as a taxonomic order are mainly found in the skull and on the hands and feet. The reason for this has to do with the fact that the hands and feet and the head are the areas of the body that interact with the environment the most and as such are are subject to the greatest amount of selective pressures.

Nails, opposable thumbs, friction ridges among other are anatomical features that have been selected for within the primate lineage and assist in the survivability of young primates.

What you are doing

Your task is to explore a primate hand features and explain how that primate hand feature enhance fitness.

Before you begin your task make sure you do the following things

Read lecture notes on primate taxonomy and chapter 6

What you have to do for points

Make sure you answer all of the following questions for full points.

1. 1. What does the arboreal hypothesis suggest about the reason why primates have unique hand features?
   2. Explain how primate hand features increase fitness and give one example. When writing about your example name the hand feature that you have chosen and explain clearly why it increase fitness in a tree environment.
      1. As part of your response include a definition of fitness in your own words.
   3. Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind.
   4. You will need to cite your work.

Tips for success

• Please keep your answer to only what is asked in the assignment.
• I recommend composing your content offline in a text editor and then copy and paste the text into your reply post. If something happens you will have an offline copy of all of your hard work!
• I highly recommend using Google Docs (Drive) to compose offline, as Google plays well with web-based forums. If you are using Microsoft Word to compose offline, you may need to do some editing to the format when you paste it into the reply.
