The relation between the tiger and the goldfish is that they are both animals that fall into the category of vertebrates. This means that both creatures have spines, and internal bone structure. This is a trait that distinguishes them from the invertebrates that have no spine and bone structure, like the octopus for example, or from the creatures that have an exoskeleton, which means they have a bone structure that is covering the body, but not inside the body itself, like the scorpions for example.

Answer:
Life is suggested to have started in an aquatic ecosystem - the ocean.
Explanation:
For decades, life has been suggested to have started in an aquatic environment due to evidence of ancient fossils and chemical studies.
Recently, scientists have been able to narrow these suggestions to state that life originated in a deep sea hydrothermal vent. This hypothesis arised due to the presence of chemicals that are thought to have produced the chemical reactions that are necessary for the evolution of life.
The first living forms on Earth were single-celled micro-organisms called stromatolites - <em>rock-like structures formed by cyanobacteria</em> - that appeared around four billion years ago. Interestingly, we are still able to find these ancient creatures but only in specific regions of the world such as Cuatro Cienegas, Coahuila in Mexico.
