the language.. please express in English
Answer: We have found fossils that share specific bony traits that are found only in all whales but absent in every other mammal group, indicating descent from a shared common ancestor with modern whales, and these fossils had legs fully adapted for walking on land, and fundamentally identical to those of older mammals that precede the shared common ancestor that these mammals share with whales.
This tells us that the shared common ancestor of whales and these mammals with legs almost certainly had legs themselves, and inherited those legs from their own older mammal ancestors.
Therefore, whales have ancestors in their lineage that walked on land with legs.
(We also have multiple fossils of ancient whales that had legs transitional in form between fully terrestrial walking legs and flippers adapted for swimming, and modern whales still possess a remnant hip bone buried deep in their bodies.)

Explanation:
There is no doubt that competition occurs, but less is known about the strength and importance of competition affecting ecosystems. The latter is not easy to get at for living organisms because the role of each organism in the ecosystem needs to be well-known. It is even more difficult for fossil ecosystems because the diet is not fully understood for each species and not all animals have the same preservation potential. Nevertheless, paleontologists have attempted to find evidence for competition between taxa. For example, they have investigated the diversity and abundance through time of two groups thought to have competed with each other by having lived at about the same time and place and having had a similar diet. For example, Sepkoski and colleagues (2000) showed that cyclostome bryozoans became much more diverse in the Cretaceous and Cenozoic, while cheilostome bryozoan diversity declined. Strong competition between these two groups with cyclostomes as the winner is an explanation for this pattern.
