This document provides an overview of animal behavior and its study from an AP Biology perspective. It discusses key concepts like innate versus learned behavior, proximate versus ultimate causation in behavior analysis, and pioneers in the field like Lorenz and Tinbergen. Specific behaviors examined include imprinting, migration, communication through pheromones and song, and social behaviors such as cooperation, territoriality and dominance hierarchies. A variety of animal examples are provided to illustrate different behavioral concepts.
Darwins concept
He was born February 12th 1809
Darwin developed the biological theory of evolution that explains how modern organisms evolved over long periods of time through descent from common ancestors.
In 1831, he began a 5 year voyage on the HMS Beagle that would change his life.
Darwin thought about the patterns he’d seen on his voyage
He realized that there were many similarities between the animals he’d seen
There was evidence that suggested that species were not fixed and that they could change by some natural process
Proposed that the use or disuse of organs caused organisms to gain or lose traits over time.
These new characteristics could be passed on to the next generation.
Lamarck’s hypotheses were incorrect in many ways
However, Lamarck was one of the first to:
Suggest that species are not fixed
Explain that evolution uses natural processes
Recognize that there is a link between an organism’s environment and its body structures
Lamarck’s work paved the way for later biologists, including Darwin
In 1798, Thomas Malthus noticed that people were being born faster than people were dying.
How this helped Darwin
He reasoned that what Malthus proposed for human populations also applied to all living things.
Struggle for Existence
From Malthus’ theory of supply and demand, Darwin reasoned that if more individuals are produced than can survive, they will have to compete for food, living space and other necessities of life
Darwin described this as the struggle for existence
Individuals have natural variations among their inheritable traits
Fast predators capture prey more efficiently
Prey that are faster, better camouflaged or better protected avoid being caught.
Any heritable characteristic that increases an organisms ability to survive and reproduce in its environment is called an adaptation’’
Ability to survive and reproduce in a specific environment is called FITNESS
Fitness is a result of adaptation
Good adaptations allow organisms to survive and are passed on to their offspring.
Good fitness: reproduce
Low fitness: few offspring/extinction
Fixed Action Pattern (FAP) is a series or sequence of acts that occur behaviorally in animals. it is also known as instinctive behaviour as it is determined by gene of an organism and exhibited automatically without having any prior experience.

Ethology is the scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Ethology is a branch of zoology concerned with the study of animal behavior. Ethologists take a comparative approach, studying behaviors ranging from kinship, cooperation, and parental investment, to conflict, sexual selection, and aggression across a variety of species.
Quranic Concept of Evolution
SUMMARY
According to the Holy Quran, the evolution of life is the result of divine will and divine guidance. The
Holy Quran declares that the harmony and complexity of creation and could not have come of its own
accord. In contrast, natural selection, the foundation of modern theory of evolution, credits accidental
mutation for the survival of life and its complexity. But it fails to explain how the life was created and
how the accidents can guide the life towards complexity.
EVOLUTION OF LIFE: DIVINE WILL, NATURAL SELECTION
The Holy Quran states that life resulted from evolution. However, this evolution was not blind or random.
Rather, evolution was controlled by Divine hand. This Divine hand accounts for the beginning, diversity
and complexity of life on Earth.
However, modern biology, which is based on Darwin’s theory of evolution, attributes evolution to the
principle of natural selection. According to this principle, humans, animals and plants, all evolved by
natural accidents. The evolution of the human body was simply the outcome of automatic natural
processes spread out over billions of years. In this immensely long process, humans evolved from onecelled
organisms without any Divine help, guidance and purpose.
Natural selection is the cornerstone of Darwin’s theory. Unlike the Holy Quran, the principle of natural
selection did not acknowledge the idea that the universe is designed by an intelligent mind.
Another difference between the principle of natural selection and the teachings of Islam is regarding the
path of evolution. Natural selection states humans and apes have evolved from a common ancestor.
Following this logic, biologists consider apes to be the most recent ancestor of humans. The Holy Quran,
however, doesn’t put forward the idea of one common ancestor and thus doesn’t regard ape to be part of
human evolutionary chain.
Natural Selection
Natural selection means that nature, not Divine Will, has guided the direction of evolution.
Three Conditions of Natural Selection
According to neo-Darwins, three conditions must be satisfied before natural selection can take place. The
first condition is reproduction – that is there must be offspring. Secondly, the offspring should vary from
the parents due to mutation, even if negligibly so. Finally, the accidental mutation in offspring should
eventually lead to differences in the ability to survive and to further reproduce. 1

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Proximate cause questions The red–crowned cranes, like many animals, breed in spring and early summer. A proximate question about the timing of breeding by this species might be, How does day length influence breeding by red–crowned cranes? A reasonable hypothesis for the proximate cause of this behavior is that breeding is triggered by the effect of increased day length on an animal’s production of and responses to particular hormones. Indeed, experiments with various animals demonstrate that lengthening daily exposure to light produces neural and hormonal changes that induce behavior associated with reproduction, such as singing and nest building in birds. Ultimate cause questions In contrast to proximate questions, ultimate questions address the evolutionary significance of a behavior. Ultimate questions take such forms as, Why did natural selection favor this behavior and not a different one? Hypotheses addressing “why” questions propose that the behavior increases fitness in some particular way. A reasonable hypothesis for why the red–crowned crane reproduces in spring and early summer is that breeding is most productive at that time of year. For instance, at that time, parent birds can find ample food for rapidly growing offspring, providing an advantage in reproductive success compared to birds that breed in other seasons.
Do humans exhibit Fixed Action Patterns? This question was addressed by Irenaeus Eibl-Eibesfeldt and Hans Hass who worked at the Max-Planck-Institute for Behavioural Physiology in Germany. They created a Film Archive of Human Ethology of unstaged and minimally disturbed social behaviour. They filmed people across a wide range of cultures with a right-angle reflex lens camera i.e. the subjects did not realize that they were being filmed because the camera lens did not appear to be pointing at them! Eibl-Eibesfeldt has identified and recorded on film, several human Fixed Action Patterns or human 'universals' e.g. smiling and the "eyebrow-flash" Eibl-Eibesfeldt took these pictures of a Himba woman from Namibia (SW-Africa). She shows a rapid brow raising (between the second and third still images) which coincides with raising her eyelids. Because all the cultures he examined showed this behaviour, Eibl-Eibesfeldt concluded that it was a human 'universal' or Fixed Action Pattern. Some Sphex wasps drop a paralyzed insect near the opening of the nest. Before taking provisions into the nest, the sphex first inspects the nest, leaving the prey outside. During the sphex's inspection of the nest an experimenter can move the prey a few inches away from the opening of the nest. When the sphex emerges from the nest ready to drag in the prey, it finds the prey missing. The sphex quickly locates the moved prey, but now its behavioral "program" has been reset. After dragging the prey back to the opening of the nest, once again the sphex is compelled to inspect the nest, so the prey is again dropped and left outside during another stereotypical inspection of the nest. This iteration can be repeated again and again, with the sphex never seeming to notice what is going on, never able to escape from its genetically-programmed sequence of behaviors. Douglas Hofstadter and Daniel Dennett have used this mechanistic behavior as an example of how seemingly thoughtful behavior can actually be quite mindless, the opposite of human behavioral flexibility that we experience as free will
The sow bugs become more active in dry areas and less active in humid areas. Though sow bugs do not move toward or away from specific conditions, their increased movement under dry conditions increases the chance that they will leave a dry area and encounter a moist area. And since they slow down in a moist area, they tend to stay there once they encounter it. In contrast to a kinesis, a taxis is a more or less automatic, oriented movement toward (a positive taxis) or away from (a negative taxis) some stimulus. For example, many stream fish, such as trout, exhibit positive rheotaxis (from the Greek rheos, current); they automatically swim or orient themselves in an upstream direction (toward the current). This taxis keeps the fish from being swept away and keeps them facing the direction from which food will come.
Bird migration, a behavior that is largely under genetic control. Each spring, migrating western sandpipers (Calidris mauri), such as those shown here, migrate from their wintering grounds, which may be as far south as Peru, to their breeding grounds in Alaska. In the autumn, they return to the wintering grounds.
But how do the young know on whom—or what—to imprint? How do young geese know that they should follow the mother goose? The tendency to respond is innate in the birds; the outside world provides the imprinting stimulus, something to which the response will be directed. Experiments with many species of waterfowl indicate that they have no innate recognition of “mother.” They respond to and identify with the first object they encounter that has certain key characteristics. In classic experiments done in the 1930s, Konrad Lorenz showed that the most important imprinting stimulus in graylag geese is movement of an object away from the young. When incubator–hatched goslings spent their first few hours with Lorenz rather than with a goose, they imprinted on him, and from then on, they steadfastly followed him and showed no recognition of their biological mother or other adults of their own species. Again, there are both proximate and ultimate explanations
Cranes also imprint as hatchlings, creating both problems and opportunities in captive rearing programs designed to save endangered crane species. For instance, a group of 77 endangered whooping cranes hatched and raised by sandhill cranes imprinted on the sandhill foster parents; none of these whooping cranes ever formed a mating pair–bond with another whooping crane. As a consequence, captive breeding programs now isolate young cranes and expose them to the sights and sounds of members of their own species. But imprinting can also be used to aid crane conservation Young whooping cranes imprinted on humans in “crane suits” have been taught to follow these “parents” flying ultralight aircraft along new migration routes. And importantly, such cranes have formed mating pair–bonds with other whooping cranes.
The luring function of sex pheromones is a perfect way for predators to get heir prey without having to work too hard. The spider Mastophora hutchinsoni spreads sex pheromones of moths, using them as allomones. This way he can lure about enough moths to sustain. When the moths fly in, convinced they are about to mate, the spider shoots a sticky ball on wire towards them. As they stick to the ball, he drags them in and eats them.
