Why zoologists name the bones of a frog like those of humans?
Zoologists name the bones of a frog similarly to those of humans because both frogs and humans share a common ancestry where many skeletal structures have similar functions and features. This allows scientists to identify and study comparable elements in different species for evolutionary and comparative anatomical purposes.
How are frog bones different than human bones?
How are they the same? The bones in a frog are inside of its body and humans are the same way. How are they different? They are different because their fingers and toes are webbed.

What are structures that have different functions in different species but develop from the same embryonic tissue?
Homologous structures are anatomical structures that share a common evolutionary origin, but may have different functions in different species. These structures develop from the same embryonic tissue and demonstrate evolutionary relationships between species. An example is the forelimbs of vertebrates, which have different functions such as wings in birds, flippers in whales, and arms in humans.
Are humans natural structures?
No, humans are living organisms, not structures. Structures are typically inanimate objects that are constructed or formed by humans, whereas humans are biological beings that are part of the natural world.
