Elephants have evolved over millions of years from small forest-dwelling animals to the large land mammals we know today. Early elephant ancestors were about the size of a dog and lived in forests in Africa and Asia as far back as 60 million years ago. Over generations, natural selection led to elephants growing larger in size to survive in more open grassland habitats, developing trunks and tusks, and living in herds for protection and survival.

Elephants
The Myanmar elephant is internationally endangered and is regarded as a worldwide flagship species. Throughout their range states, the wild elephant is severely threatened by habitat destruction, poaching, and fragmentation into small isolated groups. Many population biologists believe that nowhere in Asia is there a single wild population large enough to avoid inbreeding over the long term.

Evolution and Changes
Evolution is the process by which organisms acquire adaptations over time. There are several lines of evidence that support the theory of evolution, including:
- Comparative anatomy, which looks at anatomical similarities between species and finds homologous structures that suggest a common ancestor.
- DNA analysis, where closer genetic relationships are found between species that share more similarities in their DNA sequences.
- The fossil record, where fossils in older rock layers tend to resemble more ancient organisms, while fossils in newer layers more closely resemble present-day species.
RECOMBINANT DNA TECHNOLOGY AND ITS APPLICATION
Recombinant DNA technology has had widespread global impacts. It has applications in medicine like producing insulin, vaccines, and cancer treatments. In agriculture, it has led to herbicide and insect resistant crops as well as efforts to engineer nitrogen-fixing plants. It also has uses in animal husbandry such as producing transgenic animals. Additional applications include DNA fingerprinting for forensics, producing monoclonal antibodies, and developing diagnostic tests and gene therapies. While offering benefits, it also raises ethical issues that require ongoing research and regulation.
P glo worksheet
This student worksheet contains questions about a pGLO bacteria transformation experiment. It asks the student to define terms related to the experiment such as GFP, transgenic, E. coli, plasmids, ampicillin, and arabinose. It also asks how the student will know if the experiment was successful.
P glo presentation
The Spiller Lab at Rutgers University studies transgenic organisms. Their goal is to create a transgenic bacteria that glows in the dark by taking the GFP gene from jellyfish and inserting it into E. coli bacteria. The GFP gene will be inserted into the bacterial DNA using a plasmid called pGLO. This will allow the bacteria to produce green fluorescent protein and glow, while also conferring resistance to ampicillin, allowing the bacteria to grow on nutrient plates containing the antibiotic.
P glo lab kinesthetic
1. The document provides instructions for a PGLO lab practice involving transforming E. coli bacteria with plasmid DNA.
2. The instructions include labeling micro test tubes, spreading bacteria on agar plates, heat shocking bacteria to allow plasmid entry, and incubating plates overnight to allow bacterial growth.
3. Students are asked to cut out descriptions of 12 steps and match them to diagrams showing how to complete the bacterial transformation protocol.

Match ups answers
The document is a worksheet that asks a student to determine which of 10 animals are most closely related by matching them in pairs. It provides the names of 10 animals - African elephant, kangaroo, horseshoe crab, dugong, crocodile, mountain gorilla, ring-tailed lemur, nine-banded armadillo, three-toed sloth, brown recluse spider, emperor penguin, and possum. The student is instructed to match the animals in pairs of the most closely related.
Manatee fact sheet
Manatees are large, slow-moving aquatic mammals that inhabit coastal waters and rivers. They can grow up to 13 feet long and weigh over 1,300 pounds. Despite their massive size, manatees are graceful swimmers that typically glide at 5 miles per hour but can burst up to 15 miles per hour. Manatees give birth underwater and mothers help their calves reach the surface for their first breath. Manatees are herbivores that consume large amounts of water plants. They are classified as endangered due to hunting and accidental collisions with boats.
Match ups
The document provides instructions for an activity where students are asked to match animals based on which are most closely related. It lists 12 animals and has students work with a partner to determine relationships between the animals. It then has them write down the correct matches.
Dugong fact sheet
Dugongs are large marine mammals that graze on seagrasses along coastlines from East Africa to Australia. They can stay underwater for up to six minutes and breathe either by fully surfacing or standing on their tails. Dugongs spend most of their time alone or in small groups but sometimes gather in large herds, and mothers care for calves for around 18 months. Although now protected, dugongs were historically hunted for their meat and other products, and their populations remain vulnerable.
Evolution beaks modified worksheet
Birds have different types of beaks adapted for eating different kinds of food. The worksheet matches bird beaks to tools that represent their beak functions and has students hypothesize what each bird eats based on its beak. To test their hypotheses, students will need to research each bird species to determine if their predictions about the birds' diets match the actual types of food each bird eats in the wild.
Bird beaks lesson
This document describes the beaks, diets, and habitats of various bird species from around the world. It discusses African spoonbills, lesser flamingos, yellow-naped amazon parrots, speckled pigeons, white-faced whistling ducks, griffon vultures, red-billed hornbills, hammerkops, Egyptian geese, chestnut mandibled toucans, blue and yellow macaws, king penguins, and Magellanic penguins. Each entry provides details about the bird's taxonomy, geographical range, habitat, and diet that is adapted to its particular beak type.

The researchers aimed to bioengineer a new red fluorescent protein tag from cyanobacteriochromes in Thermosynechococcus elongatus. They transfected Jurkat cells with plasmids containing fluorescent protein tags for visualization under advanced microscopes. Electroporation and the plasmid pAcGFP1-Tubulin were found to be most efficient for transfection. Future goals include optimizing expression of their engineered 569 fluorescent tag in mammalian cells.
Barrett presentation valerie metea
The document summarizes steps taken to purify a fluorescent protein tag from a cyanobacteriochrome found in Thermosynechococcus elongatus, including:
1) Transforming E. coli with the gene for the cyanobacteriochrome tag and inducing protein expression.
2) Lysing the cells using a microfluidizer and centrifuging to remove cell debris.
3) Purifying the fluorescent tag protein using a chitin bead column.
4) Analyzing purity using SDS-PAGE gel electrophoresis and a spectrophotometer.

The document discusses engineering a red fluorescent protein tag from the cyanobacterium Thermosynechococcuselongatus for use as an easily detectable protein marker. The tag would respond to different light wavelengths and could be used to study protein expression and transformation in T. elongatus cells. Existing green fluorescent protein tags from jellyfish require a different light wavelength to be detected. The engineered red tag would use the GAF domain protein and phycocyanobilin chromophore from T. elongatus to fluorescently label and image proteins when expressed in host cells.
Monica's Barrett Presentation
This document summarizes a student research project on bioengineering fluorescent protein tags from cyanobacteriochromes found in Thermosynechococcus elongatus BP-1. The student presented on expressing genes from T. elongatus that produce cyanobacteriochromes, which are light-sensitive blue/green pigments, in E. coli cells. The goal was to engineer red fluorescent cyanobacteriochromes by using a two-plasmid system involving genes for heme oxygenase and reductase in E. coli cells containing the cyanobacteriochrome genes.
Mo's Barret Presentation
The researcher expressed the wrong fluorescent protein from Thermosynechococcus elongatus, with the pelleted proteins being blue instead of the expected yellow. Through DNA sequencing and comparison to published sequences, they determined the expressed protein was gene 0569 instead of the target gene 0911. Contamination of samples or mislabeling likely occurred. The researcher took steps to verify the correct gene, such as sequencing plasmid DNA from older stock and improving lab techniques, to obtain the expected yellow fluorescent protein in future expressions.

This document summarizes research to bioengineer a new red fluorescent protein tag from a cyanobacteriochrome found in Thermosynechococcus elongatus. The researchers aim to develop a small, photostable red tag as an alternative to commonly used green and yellow fluorescent proteins from jellyfish. They use molecular biology techniques like PCR, site-directed mutagenesis, and transfection of E. coli and mammalian cells to express and purify the mutated protein, which they characterize through spectroscopy and microscopy. The goal is to create a useful new tool for cellular imaging applications.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
