Animals have different mouth structures because of the things they eat and how they eat. For example: lions need to eat meat, so they will have a stronger jaw structure, to be able to chew and process the food. Whilst, turtles live on plants and so they will not need such a strong jaw structure...
If two different animals possess homologous structures, it means they share a common evolutionary ancestor. These structures may serve different functions in each species, but they have a similar underlying structure due to their shared ancestry.
comparative anatomy :P
It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
Similar in appearance and function (different Orgin)
comparative anatomy :P

All of the animals cell are almost same. They have the same structures, and organelle. But they have different gene. That's what makes them different from us.
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
They live in different environments. They have similar basic functions.
Embryonic structures are early formations that develop during the early stages of an organism's growth and development. These structures serve as the foundation for the formation of different body parts and systems as the organism matures. Studying embryonic structures can provide insights into the evolutionary history and development of different species.
many land animals get oxygen by breathing air into their lungs,like you do .but not all animals get oxygen this way. different structures for getting oxygen.
what types of structures help animals get energy
