Researching Evolutionary if you do not answer this correctly ill report your History
In this activity, you will compare and contrast the evolutionary history of humans and humpback whales.

Estimated time to complete: 2–3 hours

Part A
Do you think that humans and humpback whales share a common evolutionary lineage? Explain your answer.

When performing a wall sit or squat, the muscle groups that are primarily used are the muscles of the thigh, buttocks and lower abdomen, with the muscular, skeletal and joint systems interacting during the process.

Explanation:

Squats are a movement that consists of bending the lower limbs - thighs on hips and legs on thighs - that is repeatedly used as a muscle-strengthening routine.

In squats, the main muscle groups involved are :

Femoral quadriceps, on the front of the thigh. Biceps femoral, semitendinosus and semimembranous, in the posterior aspect of the thigh. Gluteal muscles. Rectus and oblique abdominal muscles.

Other thigh muscles, such as the adductors and pectineo, contribute to stabilization during movement.

The systems involved in squats are those related to the muscles, already mentioned, bones - hip, tibia femur, and fibula - and the corresponding joints:

Coxofemoral joint, between hip and femur. Knee joint, between femur and tibia-fibula.

The cooperation of these systems allows an adequate movement known as squatting or wall sitting.
