Ligaments

Ligaments are fibrous bands or sheets of connective tissue linking two or more bones, cartilages, or structures together. One or more ligaments provide stability to a joint during rest and movement. Excessive movements such as hyper–extension or hyper–flexion, may be restricted by ligaments. Further, some ligaments prevent movement in certain directions.

The bones are held together by connective tissue such as tendon, ligaments and muscles. The tendons are an elastic type of material that exert a force to assist the joints complete their movement. That is because some joints are not perfect levers.The main support for the human frame is the muscles of which there is a few types, from smooth muscle in your arteries to striated muscle which is the main muscle of the human frame.

Ligaments hold one bone to another bone.
Tendons hold muscle to a bone.
Joints allow different types of movement between two bones or not examples sutures in the skull.

Ligaments, they are a tough fiberous material that connect one bone to another at a joint. Tendons are similar but they connect muscle to the bone, allowing you to actually move the bone to which position you want. The key material involved in this connective tissue is collagen.

Religion is a belief system; evolutionary biology is not. Evolutionary biology is a knowledge system. You can't "believe in" the theory of evolution any more than you can "believe in" gravity. A skeleton the age of Lucy could not be carbon dated because carbon dating works only for fossils up to 80,000 years old. Lucy was more than two million years old. The oldest fossils of modern man are between 200 thousand and 300 thousand years old. Older fossils would be very surprising, but evidence is what it is, and scientists would interpret it according to evolutionary theory.

It's Ligaments mate here's a bit of info on just that topic.

In its most common use, a ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen fibres. Ligaments connect bones to other bones to form a joint. (They do not connect muscles to bones; that is the function of tendons.) Some ligaments limit the mobility of articulations, or prevent certain movements altogether.

Capsular ligaments are part of the articular capsule that surrounds synovial joints. They act as mechanical reinforcements. Extra-capsular ligaments join bones together and provide joint stability.

Ligaments are slightly elastic; when under tension, they gradually lengthen. This is one reason why dislocated joints must be set as quickly as possible: if the ligaments lengthen too much, then the joint will be weakened, becoming prone to future dislocations. Athletes, gymnasts, dancers, and martial artists perform stretching exercises to lengthen their ligaments, making their joints more supple. The term double-jointed refers to people who have more elastic ligaments, allowing their joints to stretch and contort further. The medical term for describing such double-jointed persons is hyperlaxity and double-jointed is a synonym of hyperlax.

The study of ligaments is known as desmology.

The consequence of a broken ligament can be instability of the joint. Not all broken ligaments need surgery, but if surgery is needed to stabilise the joint, the broken ligament can be joined. Scar tissue may prevent this. If it is not possible to fix the broken ligament, other procedures such as the Brunelli Procedure can correct the instability. Instability of a joint can over time lead to wear of the cartilage and eventually to osteoarthritis.

Hers's a bit about Tendons.

A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone, or muscle to muscle and is designed to withstand tension. Tendons are similar to ligaments except that ligaments join one bone to another. Tendons and muscles work together and can only exert a pulling force.

This about Muscles.

Muscle (from Latin musculus "little mouse" [1]) is contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells. Its function is to produce force and cause motion, either locomotion or movement within internal organs. Much of muscle contraction occurs without conscious thought and is necessary for survival, like the contraction of the heart, or peristalsis (which pushes food through the digestive system). Voluntary muscle contraction is used to move the body, and can be finely controlled, like movements of the finger, or gross movements like the quadriceps muscle of the thigh. There are 2 types of muscle movement, slow twitch and fast twitch. Slow twitch movements act for a long time but not very fast, whilst fast twitch movements act quickly, but not for a very long time.

And last about Cartilage.

Cartilage is a type of dense connective tissue. It is composed of collagenous fibers and/or elastic fibers, and cells called chondrocytes, all of which are embedded in a firm gel-like ground substance called the matrix. Cartilage is avascular (contains no blood vessels) and nutrients are diffused through the matrix. Cartilage serves several functions, including providing a framework upon which bone deposition can begin and supplying smooth surfaces for the movement of articulating bones. Cartilage is found in many places in the body including the joints, the rib cage, the ear, the nose, the bronchial tubes and between intervertebral discs. There are three main types of cartilage: hyaline, elastic and fibrocartilage.

So as you can see it's only ligaments that hold your skeleton to gether all the rest make it work.
