Why were the researchers surprised to find out how old the remains of the hobbit were ?

The biggest surprise came when the scientists dated the remains to only about 18,000 years old. This small species of human existed at the same time aş Homo sapiens, the species that modern human beings belong to. ... This supports the idea that the hobbits are actually a separate species.

Explanation:

answer; i believe the correct answer is (sporophyte);

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
