How does evolution affect living things?
Over many generations, this can lead to major changes in the characteristics of those living things. Evolution explains how living things are changing today , as well as how modern living things descended from ancient life forms that no longer exist on Earth.
How does evolution happen?
Evolution can occur by a process called. natural selection. , which results from random genetic mutations in a population. If these mutations lead to changes that allow the living things to better survive, then their chances of surviving and reproducing in a given environment increase.

What is the theory of living things?
The Cell Theory. According to the cell theory , all living things are made up of cells, which is the structural unit of living organisms, and living cells always come from other living cells. In fact, each living thing begins life as a single cell. Some living things, such as bacteria, remain single-celled.
Why do living things evolve?
As living things evolve, they generally become better suited for their environment. This is because they evolve adaptations. An adaptation is a characteristic that helps a living thing survive and reproduce in a given environment. Look at the mole in Figure below. It has tentacles around its nose that it uses to sense things by touch. The mole lives underground in the soil, where it is always dark. However, by using its touch organ, it can detect even tiny food items in the soil in total darkness. The touch organ is an adaptation because it helps the mole survive in its dark, underground environment.

Why do psychologists look at biological processes?
By looking at the biological bases of human behavior, psychologists are better able to understand how the brain and physiological processes might influence the way people think, act, and feel. This perspective also allows researchers to come up with new treatments that target the biological influences on psychological well-being.
What is the biological perspective of aggressive behavior?
The biological viewpoint, on the other hand, would involve looking at the biological roots that lie behind aggressive behaviors. Someone who takes the biological perspective might consider how certain types of brain injury might lead to aggressive actions. Or they might consider genetic factors that can contribute to such displays of behavior.
Why is biological research important?
Biological research has helped yield useful treatments for a variety of psychological disorders .
What do biopsychologists study?
Biopsychologists study many of the same things that other psychologists do, but they are interested in looking at how biological forces shape human behaviors. Some topics that a psychologist might explore using this perspective include: Analyzing how trauma to the brain influences behaviors.
Why is it important to assess differences and similarities in twins?
Assessing the differences and similarities in twins to determine which characteristics are tied to genetics and which are linked to environmental influences. This perspective has grown considerably in recent years as the technology used to study the brain and nervous system has grown increasingly advanced.
What is biological perspective?
A biological perspective is relevant to the study of psychology in three ways: 1. Comparative method: different species of animal can be studied and compared. This can help in the search to understand human behavior. 2.

Modern Biological Theories of Crime
- Neurological Theories of Crime
Neural explanations look at the structure and functioning of the central nervous system. There are several regions of the brain that criminologists and neurologists have focused on in modern biological studies of crime. The cerebral cortex makes up the outer part of the brain, and is divid… - Genetic Explanations
Genetic explanations of crime propose that genetic factors could predispose individuals to commit crimes because genes code for physiological factors such as the structure and functioning of the nervous system and neurochemistry. As in early biological theories of crime, c…
