In the evolutionary timeline, jawless fish would be the oldest fossils, as they represent some of the earliest vertebrates. Fish with jaws evolved later, marking a significant advancement in fish evolution. Fish with leg-like fins, such as those leading to the first tetrapods, would be the most recent, as they represent a transition from aquatic to terrestrial life. Thus, the relative ages from oldest to youngest would be jawless fish, fish with jaws, and fish with leg-like fins.
this is totally a personal preference. i love my very short FORCE FINS but others love their very long freeDiving fins. many factors influence a person fin preference because of individuals swimming preference, FORCE FINS use more of the calf muscle similar to short bicycle strokes, whereas a paif of long freeDiving fins use more of the whole leg. if you ask me; FORCE FINS if you ask my dive buddy: Apollo Bio-fins somebody else; a completely different answer in general though, universally; the SCUBAPRO JET FINS is the most powerful fin
To effectively use swim fins to enhance your swimming performance, focus on proper technique and form. Start by selecting fins that fit snugly and comfortably. Use them to improve leg strength, kick efficiency, and overall speed in the water. Practice different strokes and drills with fins to build muscle and improve propulsion. Remember to gradually increase your usage to prevent strain or injury.
There are a wide range of different fins available for scuba diving. Other than dive fins, these include fins such as snorkel fins, paddle fins and split fins.

Large fins are fins that are large, in size. They are the opposite of small fins, and they are somewhat larger than medium fins. They are just a bit smaller than XL fins.
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.
