someone walks by your house with their dog, and each day the dog pees on the same spot of grass. urine has a high salt concentration. what will happen to this patch of grass over time?

your grass would get brown and die

Explanation:

Salt is commonly found in small quantities in soil. But in large quantities, it stops plants from absorbing necessary nutrients such as phosphorous and potassium, and it absorbs water the plants need to survive. This can dehydrate the roots of the grass in your lawn and cause it to turn brown and die.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
