Evolution and animals structural transformation
Change yourself with environment
You have to survive
You have to strugle
With changed and uncertain environment.
You have to change yourself to cope with the situation.
It is the theory of evolution.
Once carnivorous had no horn
Now they have horn
They gain it from a evolutionary process.
They gain it due save themselves from wild animals.
You probably know about
How an orchid formed an organ
Just like bee to protect itself from irritable attack by bee.
It is a process of evolution.
Once you will be change
Your structure will be change
To cope with the environment.
