Genetically modified organisms (GMOs) can be engineered in several ways to alter plant traits. Some common applications include making crop plants resistant to herbicides, allowing farmers to spray fields without damaging crops. Corn, soybeans, and cotton in the US are often engineered for herbicide resistance. GMOs are also used to improve crop quality, increase nutrient levels, and produce pharmaceuticals and vaccines in plants. However, the ethics and impacts of GMO technology are debated, with concerns about environmental effects, corporate control of seeds and genes, and impacts on developing countries.Selection pressure
Selection pressureAftab Badshah
油
Selection pressure refers to factors in an organism's environment that give certain variations an advantage, pushing evolution in a direction. Random mutations occur during reproduction, and favorable mutations that increase survival and reproduction will become more common through natural selection over generations. A selection pressure can be anything consistent that impacts survival and reproduction rates, like availability of resources, presence of predators, or competition. Selection operates at the individual level, favoring traits that increase individual fitness even if they harm the species as a whole.Evolution presentation I & II.

Charles Darwin developed the theory of evolution by natural selection after observing variations in species during his voyage on the HMS Beagle. The document discusses the key points of Darwin's theory, including that 1) organisms produce more offspring than can survive, 2) individuals vary, 3) those best adapted to the environment survive and pass on their traits, leading populations to become better adapted over time. It also describes Darwin's observations of finches on the Galapagos Islands which provided evidence for his theory of evolution.Human evaluation

This document describes the key characteristics of several early human ancestors from Ardipithecus ramidus 4.4 million years ago to Homo sapiens (modern humans) from 120,000 years ago, noting their distinguishing physical traits such as brain size and locomotion as well as the time periods and locations where the first fossils were discovered for each species. Overall it traces the evolution of early humans from more chimpanzee-like features to the development of upright walking and increasingly larger brains and sophisticated tool usage.Biology - Chp 15 - Darwins Theory Of Evolution - PowerPoint

- Charles Darwin developed the theory of evolution by natural selection based on observations he made during his voyage on the HMS Beagle from 1831 to 1836.
- He noticed that species varied between different locations and began to hypothesize that species evolved over time through natural selection, where individuals better suited to their environment were more likely to survive and pass on their traits.
- In his 1859 book On the Origin of Species, Darwin outlined his theory that evolution occurred gradually through natural selection acting on small inherited variations, resulting in the descent of all species from common ancestors and the diversification of life over deep time.Primate Social Behavior
Primate Social BehaviorPaulVMcDowell

Primate social behavior is complex, with primates forming social groups for defense, cooperation, and raising young. Social behaviors include grooming to maintain social bonds, territoriality where groups defend core areas, and dominance hierarchies. Communication occurs through calls, gestures, and reconciliation behaviors after conflicts. While tool use is most advanced in chimpanzees, other primates also exhibit social learning behaviors that provide clues about early human societies. Comparing behaviors of chimpanzees and bonobos offers insights into how nature and nurture have shaped human social evolution."parental care of harvivore animals "seminar by Subrata paul

This document discusses parental care in herbivorous mammals. It describes how parental care varies between species, with females generally providing most of the care since males contribute little after mating. The types of parental care include maternal, paternal, and biparental care. Examples are given for several species like hippopotamus, giraffe, gorilla, and okapi. Benefits of parental care include improved offspring survival. There can also be conflicts between parents and offspring over the level and duration of care provided.

Systematics reveals patterns in organic diversity and determines the reasons behind similarities through common descent or adaptation. It also contributes significantly to applied fields like medicine, agriculture, conservation, and resource management by identifying organisms and relationships. Systematics plays a key role in theoretical biology as well, such as developing population thinking and upholding natural selection.Birds

This study used stereo photography to collect quantitative 3D data on the structure and movement of large starling flocks during aerial displays over roosting sites. The researchers were able to reconstruct the positions of hundreds to thousands of individual starlings in cohesive flocks. Their analysis characterized global flock properties like shape, size, orientation and movement. They also investigated the internal flock structure, finding non-uniform density profiles with birds packed more tightly at the edges. This data provides an empirical benchmark for testing models of collective animal behavior and insights into flocking as an emergent property of group interactions.How Does Climate Change Affect Animal Behavior

Darwin discovered 13 species of finches on the Galapagos Islands that all descended from a common ancestor. The finches have adapted to their environments by developing differences in beak type, color, and size to eat various foods like seeds, insects, or use tools. Peter and Rosemary Grant studied the finches to show there is enough natural variation within each species for natural selection to lead to changes over time, such as documenting changes in finch beak and body traits during drought.The evolution of kin selection
The evolution of kin selectionadityakuroodi
油
Kin selection theory explains the evolution of altruism. While altruism seems to go against individual survival and fitness, kin selection demonstrates that altruistic behavior can persist if the altruistic individual helps genetically similar relatives to survive and pass on shared genes. Key examples discussed are sterile worker ants helping their queen sister reproduce since they share three-quarters of their genes, and ground squirrels whose alarm calls risk individual safety but benefit genetically related neighbors. The theory was developed by W.D. Hamilton and others to explain how natural selection can favor altruism between kin.Sexual Selection
Sexual SelectionNick
油
Sexual selection occurs through male competition and female choice. It leads to the evolution of extreme traits in males that give them an advantage in attracting mates but may reduce survival. Sexual dimorphism arises when males and females of a species differ in traits, often with males developing more ornamented characteristics. Runaway selection can cause traits to evolve that do not improve quality but instead fulfill female preferences, like long bright tails in some species. Sexual selection drives evolution and speciation.Theory of evolution notes
Theory of evolution notesRachael Hubbard
油
Natural selection is the driving force behind evolution. According to Charles Darwin's theory of natural selection:
1) There is genetic variation within populations. Traits that increase reproductive success will be passed on more frequently.
2) Individuals with traits better suited to the environment will have greater access to resources and be more likely to reproduce.
3) Over time, individuals with traits that increase reproductive success will comprise a greater proportion of the population, leading populations to evolve.Foraging ecology- Optimal Foraging Theory.pptx

Introduction
Foraging theory is a branch of behavioural ecology that deals with the foraging behaviour of the organisms with respect to the environment where the organism lives.
Types of foraging : solitary and group
Foraging strategies : sit and wait , active
Optimal Foraging Theory (OFT):
Formulated by MacAorthur-Pianka (1966).
It is a behavioral ecology model that helps predict how an animal behaves when searching for food.
It states to maximize fitness, an animal adopts a foraging strategy that provides the most benefit (energy) for the lowest cost, maximizing the net energy gained.
Although obtaining food provides the animal with energy, for searching and capturing the food require both energy and time.
OFT helps predict the best strategy that an animal can use to achieve this goal.
It is an ecological application of the optimality model.
This theory assumes that the most economically advantageous foraging pattern will be selected for a species through natural selection.
Optimal foraging model
Generates quantitative predictions of how animals maximize their fitness while they forage.
The model building process involves identifying the currency, constrains and appropriate decision rule for the forager (organisms best foraging strategy).
Optimal Decision Rule
EXAMPLES
optimal number of food items that an animal should carry back to its nesting site.
the optimal size of a food item that an animal should feed on.
Optimal Diet Model:
Energy (E): amount of energy required for searching the food
Handling time (H): amount of time the predator takes to handle the food
Search time (S): amount of time the predator takes to find a prey and this is dependent on the abundance of the food and the ease of locating it
Patch departure rule :
The foragers changes the track in patch and habitat quality to save time to invest time more effectively on other patches.
Departure from a prey patch is one of the key factors determining its foraging success.
W representing the time a predator is willing to invest in the patch.
As long as no prey are captured, W declines and when it drops below critical level the patch is abandoned.
Marginal value theorem
The油MARGINAL VALUE THEOREM油is a type of optimality model that is often applied to optimal foraging. This theorem is used to describe a situation in which an organism searching for food in a patch must decide when it is economically favorable to leave.
When more energy is required for an animal to search food in this patch then the animal should leave the patch and go to another patch where more food/ resources are available. It is prediction when to leave the patch. While the animal is within a patch, it experiences the油law of diminishing returns, where it becomes harder and harder to find prey as time goes on.
Optimal foraging in bees: Wolf and Schmid-hempel (1989) showed that the cost of heavy nectar is great that it shortens the bees lifespan.

Evolutionary developmental biology examines the development of different organisms to understand ancestral relationships and how developmental mechanisms lead to evolutionary changes. It focuses on genes that control development and how changes in these genes can produce variation that is acted on by natural selection. A key example is that morphological differences between chicken and duck feet are due to different expression of BMP4 and Gremlin genes, which control cell survival and apoptosis in the developing limb. Developmental genes like Hox genes are important for pattern formation and have been pivotal in animal evolution by allowing variation and the formation of new body plans.Presentation

Molecular farming is a new technology that uses plants as bioreactors to produce large quantities of pharmaceutical substances like vaccines and antibodies. It works by artificially introducing genes into plants through the same process used in genetic modification. Plants are used as an expression system because it allows for cost reduction, stability, less time consumption, and safety compared to traditional expression systems. Molecular farming involves cloning a gene of interest, transforming a host plant, growing and processing the plant biomass to purify the product. It is primarily used for medical products like vaccines and antibodies but also has applications for industrial enzymes, polymers, and research proteins. However, there are also environmental and food safety risks associated with gene flow and contamination that need to be addressed.
