Animal Physiology: From Genes To Organisms <HIGH-QUALITY · 2026>

This "bottom-up" perspective helps explain why an animal functions the way it does, linking microscopic instructions in DNA to the macroscopic behavior of the whole animal.

How individual tissues coordinate to perform complex tasks (like respiration or digestion). Animal Physiology: From Genes to Organisms

A standout informative feature of this approach is its . Rather than looking at organs in isolation, it connects biological functions across four distinct layers: This "bottom-up" perspective helps explain why an animal

How those proteins govern cell signaling and metabolism. Rather than looking at organs in isolation, it

How these internal processes allow the organism to survive and adapt to specific environmental stressors (like extreme heat or high altitude).

How specific gene expressions trigger the production of proteins and enzymes.

"Animal Physiology: From Genes to Organisms" (primarily known as the textbook by Sherwood, Klandorf, and Yancey) is built around the .
