Tobi says: Bird's bones are hollow to help them fly,obviously to reduce weight when they fly. Human bones, on the other hand, are not hollow. We need strong bones to do the things we do, eg: walking, skipping, jumping etc...
Animals like insects, have exoskeletons-basically they have no bones, and only have tough,protective, often shell like skin. Animals like cats, dogs, horses, giraffes and and birds are all endoskeletons- they have bones, and those bones are internal (on the inside of the skin).
The relationship between a humans pregnancy length and average life span is not so different than other mammals. It appears to be closely related to size.
Because people kept finding their fossilized bones as well as complete animals frozen in the permafrost of Siberia. There aren't any of those animals living now so they must be extinct.
in what ways are the functions of the organ systems of plants similar to those animals
The Ancient Egyptians domesticated many different types of animals - sheep, cattle, goats, pigs, geese and later horses.
In one sense, since humans are animals, your brain does not differ from the brina of an animal. human brains, and those of the other great apes, do differ from those of other animals in size relative to body size. In addition, human brains have structured that some other animals, reptiles, for example, lack.

Human bones are thicker and denser; bird bones are thinner, hollow and mean less weight on the bird.
It depends on the animal. There are thousands of different animals and thousands of different species of those animals.
A baby has over 300 bones to begin with, and by adulthood, those bones form with other bones and cartilages, resulting in about 206 bones in his/her body.
The hand is part of the human body that has 27 bones. Out of the 27 bones eight of those bones are in the wrist.

Have different animals have babies then let those babies have babies with different animals.
Bones can decay like any other organic material. Sometimes, however, bones can be preserved in rock - those are called fossils.
Humans have unique vitamin requirements compared to other animals because our bodies cannot produce certain essential vitamins on their own, so we must obtain them from our diet. This is different from many animals that can synthesize these vitamins internally.
If you're asking about the joinings of the different bones, those would be "sutures".
