What does it mean to say that two different species of organisms are closely related? They have a common evolutionary ancestor.
Similarly, unrelated organisms may be distantly related, but appear very similar. This usually happens because both organisms developed common adaptations that evolved within similar environmental conditions.
Are the bones arranged in similar ways in each animal? same function, different structure. or some apparently unrelated animals have organs with similar functions, yet are very different in structure and form. What function of the butterfly and bird wing share? The same function.
Comparative embryology shows similarities between organisms that do not appear to be similar as adults because many features of embryos disappear by adulthood. For example, all vertebrate embryos have a tail and gill slits, but these disappear by adulthood in many vertebrates, including humans.
Even though frogs don’t look much like people on the outside, their skeletons are similar to people’s skeletons, especially when it comes to their limbs. Just like in a person’s arms, in a frog’s front legs are bones called the humerus, the radius and the ulna. However, a frog’s radius and ulna are fused into one bone.
Without your skeleton, you could not stand or even move.
Sharks, skates, rays and chimaeras stand apart from other jawed vertebrates in having a skeleton that is made primarily of cartilage rather than bone.
In vertebrates the adult skeleton is usually formed of bone or cartilage—living substances that grow with the animal, in contrast to the many types of invertebrate skeleton that do not grow or are dead secretions, deposits, or crystals. … The axial skeleton consists of the skull and the vertebral column.
Cartilage is less dense and therefore lighter and more flexible than bone. … In the embryos of bony vertebrates, the endoskeleton is initially formed from cartilage that is converted to bone during development. Bone tissue is also associated with bone marrow in many vertebrates.
Exoskeleton is mainly found in the vertebrates like reptiles, fishes and mammals. It is the living structure which protects the internal organs. Freshwater mussel belongs to the family Mollusca which are invertebrates. It contains soft inner body and a rigid outermost shell.
All animals have skeletons of one sort or another. Mammals, birds, reptiles, amphibians and fish have bony skeletons. These skeletons come in all shapes and sizes, but they also share common features. … The museum holds hundreds of skeletons – of fish, amphibians, reptiles, birds and mammals.
The skeletal system is a network of many different parts that work together to help you move. The main part of your skeletal system consists of your bones, hard structures that create your body’s framework — the skeleton. There are 206 bones in an adult human skeleton.
Vertebrates tend to be larger than invertebrates, thanks to their backbone, which allows their bodies to grow larger and move faster than many invertebrates.
Not So Many Species
One reason is that vertebrates are usually larger than invertebrates. They need more space. Another reason is that, even though they are more advanced, there are many limitations on the environments that are available to them. … Those nicer areas can only support so many species of animals.
