The trochanter is a lateral projection of the femur (the longest bone in the human body) in the upper part of the thigh, that is, an irregular and large prominence of the femur. The greater trochanter is a prominent and relatively easy to palpate structure belonging to the femur, and serves as an insertion to many muscles that participate in the movement and stability of the hip. The lesser trochanter is less prominent and impossible to palpate due to its internal situation, it serves as an insert for some muscles such as the iliac psoas, one of those in charge of hip flexion.
A theory of evolution that states that a species evolves in spurts of rapid change and then goes through periods of no change is known as <span>punctuated equilibrium.</span>
