From the beginning of the science, there are several scientific investigations that took place to propose a hypothesis and test these by scientific methods if these are true or not.

The some of the real life examples of the result of these scientific investigation are

Technology that helps humanity by several possibilities, helps in the transportation, medicine or health sector by developing drugs, and electricity that helped daily life of a human as vital resources.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
