Typical whale-like traits apparently the earliest to appear where the webbed feet (turning into fins), whale-like teeth, shorter legs with big feet, and whale like hearing with ear bones (ear structure). All of the other traits like fins, snake-like seamless body, nostrils shifted back, hind legs reduced and eliminated, strong swimming tail with flukes form, and small neck and long head appeared to evolve much later, this is because the organisms have to adapt to the environment and ecosystem around them and that takes time.

Missing links are place holders used when a transitional fossil cannot be found to fill in the evolutionary tree. As each new “missing link” was found, there are numerous other gaps that have to be found, so it keeps on going because scientist find new species every time they look for “missing links” to fill in the gap. The relationship between gaps and fossils is that there will always be missing patterns that lead up to the final or current species. For example, whales moved from land to water as evolutionists say. There must be an animal that had lungs and four legs, if there is no fossil proof for transitional species they are placed as missing. This occurs every time a non-predicted fossil is discovered.

The phrase “ontogeny recapitulates phylogeny” means that during its developments an organism passes through stages that are similar to its adult ancestors. The significance is that the development of an organism reflects stages through the organism’s species is passed through the evolution of it, without the vestigial organs that were once needed for the common ancestor, the evolution wouldn't have occurred correctly. For example, in a chicken, if the chicken did not have the required vestigial organ in the common ancestor of the chicken organism then the chicken would not have one or more
