Aboy inherits genes for tallness, but his growth is limited as a result of poor nutrition. this is an example of-

Growth that is limited by a result of poor nutrition is an example of Micronutrient Deficiency. Micro-nutrient deficiency is a lack of micro-nutrients which are fluoride, iodine, iron, zinc. In order to complete the deficiency kids should drink a vitamin supplement in order to overcome this deficiency. 

there have been several cases where fossils of the same type and age where found on different continents.

For example:-

"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.

This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."

But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.

i hope this helps.

have a great day ahead :)
