the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.

this happened on tam airlines.

a 50-something year old white woman arrived at her seat and saw that the passenger next to her was a black man.

visibly furious, she called the air hostess.”what’s the problem, ma? ” the hostess asked her

“can’t you see? ” the lady said – “i was given a seat next to a black man. i can’t seat here next to him. you have to change my seat”

– “, calm down, ma” – said the hostess

“unfortunately, all the seats are occupied, but i’m still going to check if we have any.”

the hostess left and returned some minutes later.

“madam, as i told you, there isn’t any empty seat in this class- economy class.

but i spoke to the captain and he confirmed that there isn’t any empty seats in the economy class. we only have seats in the first class.”

and before the woman said anything, the hostess continued

“look, it is unusual for our company to allow a passenger from the economy class change to the first class.

however, given the circumstances, the commandant thinks that it would be a scandal to make a passenger travel sat next to an unpleasant person.”

and turning to the black man, the hostess said:

“which means, sir, if you would be so nice to pack your handbag, we have reserved you a seat in the first class…”

and all the passengers nearby, who were shocked to see the scene started applauding, some standing on their feet.”
