Read God's rules of health and sanitation for Israel in Lev. 11:1-8 and Deut. 23:12-14. How might these

rules have protected His people from diseases such as

those caused by parasitic worms? Relate your answer

to the mode of transmission of many parasitic worms.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

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.
