Humans have to carry all of their weight upright and on just two legs. Animals that have four legs to support their weight and their pelvic bones are less massive. We "pay" for this as we are more prone to fractures and other problems of the upper leg bones.

Why do snakes have pelvic bones?
Snakes have pelvic bones as remnants of their evolutionary history when their ancestors had hind limbs. These pelvic bones have been greatly reduced in size and are not functional for walking or supporting legs, but they still play a role in supporting reproductive organs.
2 bones that form the pelvic bone?
The Illium, pubis, and the ischiumilium, sacrum, ischiumtwo coxal bones that articulate with each other anteriorly and with the sacrum posteriorly. The pelvic girdle performs three functions; bears weight of body, serves as place of attachment to legs, protects organs of pelvic cavity including urinary bladder, and reproductive organs.Ischium, Ilium and pubis.2 ox coxae and the sacrum
Why are the bones of the pelvic girdle larger than the bones of the pectoral girdle?
The pelvic girdle supports more weight and pressure due to the upper body resting on it while standing and moving. It also provides protection for internal reproductive organs. Additionally, the pelvic girdle is involved in weight-bearing activities such as walking and running, requiring larger and stronger bones for stability and support.
Boa constrictors have tiny pelvic girdles and legs bones within their bodies that are nonfunctional what is that called?
The nonfunctional vestigial pelvic girdle and limb bones in boa constrictors are referred to as pelvic spurs or pelvic vestiges. These remnants are thought to be remnants of their evolutionary history when their ancestors had functional legs.
Lower limb bones are attached to the axial skeleton by what?
Lower limb bones are attached to the axial skeleton by the pelvic bones, specifically the sacrum which connects to the hip bones to form the pelvis. This connection is important for weight-bearing and locomotion.
What bones of the human body differ in males and female?
The shape of the pelvic bones and the frontal bones differ.
How does the pelvic girdle size of fish compare to those of land animals?
Fish do not have "pelvic girdles" per se. Land animals in large majority have skeletal structures in their hips known as pelvic bones. In humans, men have a narrow pelvic size and women have a wider pelvic size. This is because women bear babies. The circular shape of these pelvic bones are referred to as the "pelvic girdle". Fish, however, don't have hip bones. Living in the water has eliminated the need for the extra physical support those bones would give during pregnancy. Since fish range in size from near-microscopic up to the immense whale shark, the equivalent to the pelvic area would vary greatly in size. Mammals too, range widely in size so comparison is difficult without a more specific question.
What are the bones in a shrew?
Pelvic
Is another name for pelvic bone?
The pelvic bones, or "hip bones" are also called the innominates, the OS coxae or the pelvis.
Can your penvis bones heal?
If you mean pelvic bones then yes, they can.
Why do snakes have pelvic bones?
Snakes have pelvic bones as remnants of their evolutionary history when their ancestors had hind limbs. These pelvic bones have been greatly reduced in size and are not functional for walking or supporting legs, but they still play a role in supporting reproductive organs.
Why do four legged animals have a smaller pelvis?
Pelvic size generally correlates with the size of the animal and varies with the structure of the animal and how it uses it's limbs for locomotion. The size, structure and orientation of a bipedal animal's pelvis is allows for vertical attachments of the bones and muscles of the legs...
What are bones of the pelvic girdle?
Ilium and ischium
Do the pelvic bones help your intestine?
yes
Why is the pelvic bone of a four legged animal much less massive than those of the human?
because animals have more bones and they produce more
What are the nonfunctional structures of tiny pelvic girdles and legs bones within the bodies of boa contrictors?
These are the remnants of the arms and legs that the ancestors of snakes had. Over time the limbs evolved to be smaller and smaller, until now the limbs are not visible externally but can be see as vestigial bones on a radiograph.
What are the bones that makes up the center of the skeleton?
The pelvic bones (the ilium and the ischium).
