Low survival rates of jaguar cubs can be attributed to several natural factors, including predation from larger animals, competition for resources, and environmental challenges. Cubs are vulnerable during their early months, making them easy targets for predators. Additionally, factors like habitat loss, food scarcity, and disease can further impact their survival. Ultimately, these challenges contribute to the overall low survival rates of jaguar cubs in the wild.
Survival of da fittest
In a sense, one might say that this is the case. But in a more direct sense, natural selection determines which organisms do not get to procreate (as much). Natural selection is therefore more a limiting phenomenon than an enabling one.
Animals that may have glided as in flying squirrels, used this for escaping predators. the primitive bat could have evolved into the modern bat today. Obviously the animals with better survival workings get the girl.
The salmon's journey exemplifies "survival of the fittest" through its remarkable adaptations for reproduction and survival. As they migrate upstream against strong currents, only the strongest and most resilient individuals reach their spawning grounds, ensuring that their genes are passed on. Those that can navigate obstacles and evade predators are more likely to reproduce, highlighting the importance of physical fitness and adaptability in natural selection. This cycle demonstrates how environmental challenges shape species and contribute to evolutionary success.
Anacondas are apex predators and have few natural predators in the wild. However, large caimans, jaguars, and humans are known to prey on anacondas. Additionally, young anacondas may be hunted by birds of prey, larger snakes, and other carnivorous mammals.
Survival of the fittest would be used to describe this situation.
Natural selection is based on mutation. Every being is born with mutations. Some are visible and most of them not at all and make no difference for survival. Those who are insignificant for reproduction or survival are sometimes also passed on to the next generation and to the next and so on. Over a long period of time this can make a difference although it might be not important for death or survival. Some characteristics might have had an advantage but is not obvious for us to say.
"Survival of the fittest" best describes this situation.

Yeah,I think there might be! A specialist in survival seems possible!
That's entirely a matter of perspective. From a perspective favouring robustness, one might say that natural selection is good because it usually favours the robustness of both individual populations and their ecologies. It allows survival of the fittest. But from a perspective of individual rights, one might say that natural selection is bad because it can deny individuals the right to happiness, reproduction or even life.
