Overview
In simpler terms, Evolutionary Genetics is the study to understand how genetic
variation leads to evolutionary change.
Evolutionary Genetics attempts to account for evolution in terms of changes in gene
and genotype frequencies within populations and the processes that convert the
variation with populations into more or less permanent variation between species.
The central challenge of Evolutionary Genetics is to describe how the evolutionary
forces shape the patterns of biodiversity.
Evolutionary Genetics majorly deals with;
a. Evolution of genome structure
b. The genetic basis of speciation and adaptation
c. Genetic change in response to selection within populations
Embracing GenAI - A Strategic ImperativePeter Windle
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.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
8. Evidence of Evolution:Molecular Biology Notice that a Chimp is more genetically related to a human than to an Old World Monkey!
9. Adaptive Evolution Natural Selection = Editing The finches of The Galapagos Islands: The original finch developed into 14 different species. What was the cause for the offshoots?
10. Darwinism Meets Genetics A population is the smallest unit of evolution. Natural selection acts on individuals. However the evolutionary impact of natural selection is only apparent in tracking how a population changes over time. Population Genetics emphasizes the extensive genetic variation within populations and tracks the genetic make-up of populations over time. Not all variation in a population is inheritable. Only the genetic component of variation is relevant to natural selection. Many variable traits in a population result from the combined effect of several genes. Polymorphism
11. Analyzing Gene Pools A Gene pool consists of all alleles (different forms a gene may have for a trait) in all the individuals making up a population. A reservoir for the next generation’s genes. Recall: Homozygous (RR) and Heterozygous (Rr) Dominant and Recessive (rr) Hardy Weinberg Formula (1908) Helps to calculate the frequencies of genotypes in a gene pool from the frequencies of alleles and vice versa. p2 + 2pq + q2 = 1 p = RR pq = Rr q = rr
12. Practice Using The Hardy-Weinberg Formula p2 + 2pq + q2 = 1 p = 0.6 q = 0.4 What are the genotypic frequencies of their offspring? 0.36 + 2(0.24) + 0.16 = 1 36% RR 48% Rr 16% rr
13. Microevolution 1. Genetic Drift Def: A change in the gene pool of a small population due to chance. The best measure of Darwinian fitness is the number of fertile offspring an individual leaves.
14. Genetic equilibrium- allele frequencies remain constant. To maintain equilibrium… Random mating Population must be very large No immigration or emmigration No mutations No natural selection
15. Types of Genetic Drift a. The Bottleneck Effect An event that usually reduces the overall genetic variability in a population. b. The Founder Effect Genetic Drift in a new colony i.e. The Galapagos Islands
16. Microevolution Cont. 2. Gene Flow Def: The genetic exchange with another population. 3. Mutations A change in an organism’s DNA sequence. Ultimate source of genetic variability. 4. Natural Selection Directional Selection (selecting in favor of an extreme phenotype) Disruptive (Diversifying) Selection (leads to a balance between two or more contrasting phenotypic forms) Stabilizing Selection (maintains variation in a narrow range)
23. Pre-zygotic (factors that impede mating between species or hinder fertilization of eggs if mating is attempted)
24.
25. Mechanisms of Speciation Allopatric Speciation A population forms a new species while geographically isolated from its parent population. Sympatric Speciation A small population becomes a new species in the midst of a parent population

33. Meteor of this size would have lowered the temperature of Earth due to the blocking of the sun by atmospheric dust. Theory: 65 million years ago a catastrophic event occurred killing off the dinosaurs and about ½ of the species inhabiting the Earth in a 10 million year time span.
34. The Origin of Life Stage 1: Abiotic Synthesis of Organic Monomers Amino Acids Chains of nucleotides Chains of DNA bases Chains of RNA bases Building blocks of protein Sugars Lipids ATP
35. The Origin of Life Stage 2: Abiotic Synthesis of Polymers Monomers, such as amino acids, spontaneously fused together to form proteins.
36. The Origin of Life Stage 3: Origin of Self-Replicating Molecules inheritance Ribozyme: catalytic RNA used to fuel RNA replication
37. The Origin of Life Stage 4: Formation of Pre-cells Molecular packages with some properties of life. The gap between pre-cells and true cells is enormous! Natural Selection
38. The origin of eukaryotic cells Endosymbiotic Theory Membrane bound nuclear material Organelles More complex than prokaryotic cells Ancestors to fungi, plants and animals
39. Concept Map Section 17-2 Evolution of Life Early Earth was hot; atmosphere contained poisonous gases. Earth cooled and oceans condensed. Simple organic molecules may have formed in the oceans.. Small sequences of RNA may have formed and replicated. First prokaryotes may have formed when RNA or DNA was enclosed in microspheres. Later prokaryotes were photosynthetic and produced oxygen. An oxygenated atmosphere capped by the ozone layer protected Earth. First eukaryotes may have been communities of prokaryotes. Multicellular eukaryotes evolved. Sexual reproduction increased genetic variability, hastening evolution.
