What are the 2 types of aggression?
What are the 2 types of aggression?
Two major types of aggression, proactive and reactive, are associated with contrasting expression, eliciting factors, neural pathways, development, and function. The distinction is useful for understanding the nature and evolution of human aggression.
Where does human aggression come from?
Aggression is controlled in large part by the area in the older part of the brain known as the amygdala (Figure 9.5, “Key Brain Structures Involved in Regulating and Inhibiting Aggression”). The amygdala is a brain region responsible for regulating our perceptions of, and reactions to, aggression and fear.
Why did humans become so smart?
This hypothesis posits that human cognitive complexity arose as a result of the higher level of social complexity required from living in enlarged groups. These bigger groups entail a greater amount of social relations and interactions thus leading to an expanded quantity of intelligence in humans.
How old are intelligent humans?
Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They’re followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.

Do Dinosaurs Still Exist?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
What year did dinosaurs exist?
Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.
What came before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
What came after dinosaurs?
After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. Many scientists who study dinosaurs (vertebrate paleontologists) now think that birds are direct descendants of one line of carnivorous dinosaurs, and some consider that they in fact represent modern living dinosaurs.
What killed dinosaurs?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.
How many dinosaurs were there on Earth?
900
Can we stop an asteroid?
No attempts are made to stop the asteroid, however, people desperately search for bunkers to hide in before the comet strikes.
Why did all the dinosaurs die?
The instantaneous devastation in the immediate vicinity and the widespread secondary effects of an asteroid impact were considered to be why the dinosaurs died out so suddenly. Asteroids are large, rocky bodies that orbit the Sun. They range from a few to hundreds of metres in diameter.
