Principle 2: Overproduction and the Struggle to Survive
Principle 3:Different Survival and Reproduction (Survival of the Fittest)
In the savanna, the tiger, which weighs 25 tons, is on its own to hunt for food. There is a deer that weighs 50 tons near by, also alone.
Principle 4: Change in the Gene Pool
Since there is only one of each yet a big weight difference, the bigger one will always win. The deer's weight is too much for one tiger to attack alone and eat. There is a little bit of tigers to take on big prey.
Organism: Tiger Environment: Savanna Trait Selected for: Hunting in a group Adaptation Types: Behavioral Learned
Due to there being one tiger for one prey, the tigers don't successfully find food and die. The deer are more fit and survive rather than the tigers.
The tigers realize that they can't hunt alone and gather up in a group to catch their new prey. They wait patiently until they make their move. They attack it all together and successfully bring the deer down. They now hunt as a group to survive and reproduce.
