Does mermaid really exists?

Humans can more advanced now and is highly civilized civilization ,Human can reach to outer space and succesfully landing in our natural satellite THE MOON ,but humans means we people donot know our planet fully manner in any way .
our earth has covered with 75%of water and only 25%is left i.e earth
Water is living object i tell u people about water is alive or dead object .

Q Now does mermaid exists?
The answer is:yes mermaid exists and they live in deep in oceans i dont make a story i read it in various places videos blogs etc its not a story its true.

Now the question comes ,How they exists and how they looks like us?
Darwin take a concept of theory of evolution
It means that every individuals or living object adapts environment and change itselfs according to the environment,its true but his theory is totatly wrong that humans evolute from Chimpanges because if we evolute from monkey then why monkey is still monkey why they are not evolute its true evolution changes ocurs.
But its depend on the power of brain ,our brain is so much developed we also not know about our brain fully humans adapts environments but not evolute from monkeys.
I tell you people about humans origin in other blogs.
Now our topic is mermaids ,Humans are originated and for years human eat other animals as food and they also eat marine animals like fishes and in some time humans go for taking fishes and the environment become harsh and they trapped in an islands in ocean and the only source for food there is marine animals and for some years they go deeper in oceans and their body modifies like webs in hands

There various mermaid body are recovered in various times and from years but these type of information are not open to peoples by marine departments
Its similar example is bear

He change itself according to environment and turn into polar bear
