Survival of the fittest

Today, Let’s explore into something of Biology.

Dinosaurs must have been the fittest at that time. But, they had suddenly lost the status and no longer could they keep their prosperity. Now a days, they say collision of huge meteorite on the Earth is the most convincing theory of that large scale extinction of dinosaurs.

The terminology Survival of the fittest was introduced by Herbert Spencer and it may have its significance provided that the environment around a biological form is well stabilized.

Turning to another species, mammals, which have gained prosperous status since the extinction of dinosaurs, I am wondering if it can be considered as one of the fittest or not.

Mammals have attained the function of uterus, their body was relatively small, they were of omnivore nature, the functionality of regulation of body temperature and metabolism was highly sophisticated one etc. By setting the basis of a theory on the environment after that big impact, logically it seems, mammals were the winner and dinosaurs plummeted down to the bottom line “To Be Extinct Species”, like giant killing.
(Thinking of a family of dinosaurs, it’s just a sad story to me. In modern days, once war has broken out the same happens.)

Here at this point, if I say “I think it is not convincing of characterizing it as Survival of the fittest”, may be, ones say “You again, saying such a thing, L.O.L” and I will be handled by them with their courtesy as like a drunken guy lamenting at something illogical.

But, I will persist little bit further on this issue today.

Indeed, mammals had already defeated dinosaurs, it looks like. Though mammals were thriving through in somewhat humble life at the feet of dinosaurs it really had been able to overcome the risks some biological forms were always facing at

Having laid eggs, then the dinosaurs have to protect them staying there while mammals can move around with uterus, in it the baby protected, so that they can find food at the same time. Also, mammals can keep its body temperature against now ever abnormally fluctuating atmosphere. In this regard, before the big impact, dinosaurs had already been defeated completely.

Though it is a key factor for survival to fit into something, too much and too deeply be fitted may cause some kind of adversary effect, I wonder.
If we express this victory of mammals with some words, we may say, “Overcome”, ”Flee From Bondages”, or “Relief From Binding” or “Getting The Power Of Freedom!” etc. Something like those, aren’t they?

The origin of life forms on ground is ocean on which they had depended on deeply, heavily and physically. When they ventured to ground, they had been obtaining gradually the function of ocean by integrating it into their own body. That’s why they succeeded. So, from this point of view, we may possibly say, “They get the freedom, by cutting the chain of strong tie, become independent (to some extent) of ocean”.

This, the specie that attained the freedom is in some cases found in the group of defeated in the world or environment up to that time. This fact should be worth considering. In a past, there was such short sentence in a book as “Winner will never evolve”.

After all, “won” it looks but “defeated” it really is, perhaps.

Someone may say, “The one that can fit well to transition could survive”. The statement sounds somewhat close to the above argument nevertheless once fitting is achieved, another binding will emerge by the very fitting. So, maybe, the expression or theory of “Get The Freedom” or the sorts could best fit, rather than Survival of the fittest.
