The answer would be analogous and convergent evolution. In evolutionary biology, convergent evolution is the procedure whereby creatures not carefully related, self-sufficiently evolve alike traits as an outcome of taking to familiarize to like surroundings. The beaks can be described as analogous since there is a similarity of structures that came from different origins.
These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Answer and Explanation:
1. The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body's back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them.
2. The similarities exist because all the vertebrae have to promote the support of the body, the back being the most appropriate place for them to establish themselves.
3. The differences are related to the function and type of support that each vertebrae promotes, the higher the level of systemization, the larger and thicker the vertebrae must be.
4. The caudal vertebrae should be similar to the vertebrae of the coccix, since a tail would be a representation of elongation of the coccix. We can reach this conclusion through the analysis of images that promote the visualization of this area of the body.
