Population ecology is the study of these and other questions about what factors affect population and how and why a population changes over time. Population ecology has its deepest historic roots, and its richest development, in the study of population growth, regulation, and dynamics, or demography.
When giraffes walk, they move both legs on one side of their body and then both legs on the other side; this is unique to giraffes. However, they run in a similar style to other mammals, swinging their rear legs and front legs in unison. They can reach 55 km/h (35 mph) at full speed but only in brief spurts.
Giraffe neck bones are just bigger. You have over 230 moveable and semi-moveable joints in your body. You have 27 bones in your hand. You have 14 bones in your face. The smallest bone in your body is the stirrup bone in the ear, which measures 1/10 of an inch. The longest bone in your body is the femur (thigh bone), which is about 1/4 of your height.
