Innate behaviour is behaviour you are born with, behaviour which you inherit because it is in your DNA. It is instinctive behaviour. For example, a spider knows how to spin a web as soon as it is born, or a baby can suckle because it is instinctive. The behaviour is intrinsic which means it will be present even if an animal is raised on its own, without parents or others of its species to teach it. It is also stereotypical which means the behaviour will be performed in the same way each time.
Innate behavior is thought to be inherited through genes, and it can't be changed by the individual, it is inflexible. It can be very complex and it does not have to be learned, it will be fully developed from birth. Innate behavior is beneficial, and because it is encoded in DNA it is subject to natural selection. This means overtime the genes that cause the best behavior will become more common among the individuals of a species.
A reflex is an example of innate behavior, like when you automatically pull your hand away from something that is hot. You don't have to think about it, you didn't have to learn to do it... as a human, it's just something that you do.
A scientist named Lagerspetz tried to prove that innate behaviour has a genetic base by selecting very aggressive mice, and breeding them together. Aggressive mice would cross an electrified grid to attack an opponent or would choose an opportunity to fight rather than remain peaceful. The results were compared to a control of mice with non-aggressive genetic lines. The result showed that a few genes affect variation in fighting behaviour: when aggressive mice were bred together aggressive offspring were produced. Winning enhanced fighting behaviour of aggressive animals but not of initially non-aggressive animals.
However, it is difficult to find purely innate behavior because a lot of an animal's behavior is the result of an interaction between genes and the environment. Environmental conditions can alter innate behavior. There are 5 characteristics of innate behavior that you need to remember.
It is heritable so it is passed on through DNA
It is intrinsic so it is present in animals raised in isolation from others
It is stereotypic so the behaviour will be performed the same every time
It is also inflexible so it never changes, even because of experience
And finally the behaviour is fully developed or expressed at first performance, it is consummate. So, innate behavior is a pattern of inherited or pre-set behavior that doesn't require learning or practice.
A behavior is the way an organism becomes another organism or the environment .
Learned behaviors are behaviors in which animals are NOT born with.
Inherited traits are behaviors that animals inherit from their siblings.
Determine whether each characteristic is connected to either learned or innate behavior (feel free to look back at the slides if you're unsure)
IT is INTRINSIC
IT is PROGRESSIVE
IMPRINTING is a form of...
IT is INFLEXIBLE
IT is ADAPTABLE
Try to distinguish which traits would be inherited or learned, YOU GOT THIS!!

Immunity is often challenged by the invasion of bacteria, viruses, fungi, and other pathogens. This requires the resources of the innate and adaptive immune system to protect the body. Supporting both arms of the immune response with nutrients is a vital aspect of maintaining a healthy immune system.
The innate immune response is the first line of defense, where white blood cells engulf and digest pathogens through a process called phagocytosis. If necessary, the immune system will initiate the adaptive immune response to support the innate response.
The adaptive immune system includes a more specialized, targeted attack with T cells and B cells attacking pathogens and creating antibodies. The immune response, like other critical processes in the body, require adequate nutrition to function at its best. Two critical immune nutrients for strong immune function are zinc and vitamin D. Also important for immunity is a balanced diet with plenty of fruits and vegetables.
Your body is constantly . When these get inside your immune system has two types of responses - innate and adaptive. The innate immune system is your first . It's composed of standard that eat pathogens. But some pathogens are too strong or clever for them.
That's where the specialized T- and B-cells of your adaptive immune system come in that like secret agents study pathogens. B-cells so that your innate immune system can find and eat them, while T-cells themselves.
Your immune cells do all this work to protect you automatically but they do ask for a simple thing in return: . Two critical immune nutrients are which help immune cells work more effectively. But depending on your diet and lifestyle, many people are deficient in both. That's why daily can help ensure you're giving your innate and adaptive immune cells the nutrients they need.
