the answer is gene flow
After the coelom developed in early animals, a process called spiral cleavage and determinate cleavage allowed for the evolution of many types of protostomes. This process resulted in differences in developmental processes, leading to various body plans and morphological diversity among protostomes.
Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.
The evolution of a coelom (body cavity) allowed for the development of more complex organ systems in animals. It provided protection for internal organs, allowed for greater mobility, and facilitated more efficient circulation of nutrients and waste within the body. Overall, the presence of a coelom played a key role in the diversification and evolution of multicellular organisms.
Charles Darwin work was so important because he invented the theory of evolution
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
No, a flatworm does not have a body coelom.
It was appeared in nematodes.Annelides had first true coelom.
It was where he developed his theory. The Galapagos are considered the "Laboratory of Evolution." Evolution is easily observable here.
Charles Darwin explained Evolution and figured out how it worked.
Yes, birds have a body cavity or coelom. Mammals have two separate body cavities (peritoneal / abdominal and thoracic/ chest) but birds do not have a diaphragm, and so have only one cavity.
