The document outlines key concepts around evolution, including natural selection, adaptation, and resistance. It discusses how Charles Darwin observed that organisms differ slightly and those with traits better suited to their environment are more likely to survive and reproduce, passing on those traits. Over time, this leads to evolution as populations change. It also discusses how humans have directed evolution through artificial selection of crops and livestock.
Understandings:
The distribution of species is affected by limiting factors
Community structure can be strongly affected by keystone species
Each species plays a unique role within a community because of the unique combination of its spatial habitat and interactions with other species
Interactions between species in a community can be classified according to their effect
Two species cannot survive indefinitely in the same habitat if their niches are identical

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
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

4. Today’s Objectives
Define natural selection, evolution, adaptation,
artificial selection, and resistance.
Explain the process of evolution by natural
selection.
Articulate the concept of adaptation.
Explain the steps by which a population of insects
becomes resistant to pesticide.
5. Warm Up (Feb. 29)
) List the four major levels of ecological
organization in the correct order.
t What is a population?
t Why are habitats important?
6. “The Main Man”
• Charles Darwin observed
that organisms in a
population differ slightly
from each other in form,
function, and behavior.
• Darwin proposed that some
individuals, because of
certain traits, are more likely
to survive and reproduce
than other individuals.
7. Evolution by Natural Selection
• Natural selection is the
process by which individuals
who are better adapted to
their environment, survive
and reproduce more
successfully than less well
adapted individuals do.
• Evolution is a change in the
characteristics of a population
from one generation to the
next.
9. “Survival of the Fittest”
(nature selects)
• Darwin thought that nature selects for certain
traits, such as sharper claws, because
organisms with these traits are more likely to
survive.
• Over time, the population includes a greater and
greater proportion of organisms with the
beneficial trait.
• As the populations of a given species change, so
does the species.

13. Today’s Objectives
Define natural selection, evolution, adaptation,
artificial selection, and resistance.
Explain the process of evolution by natural
selection.
Articulate the concept of adaptation.
Explain the steps by which a population of insects
becomes resistant to pesticide.
20. “Survival of the Fittest”
(nature selects)
• An example of evolution is a population of deer
that became isolated in a cold area.
• Some of the deer had genes for thicker, warmer
fur. These deer were more likely to survive, and
their young with thick fur were more likely to
survive to reproduce.
• Adaptation is the process of becoming adapted
to an environment. It is an anatomical (body
parts), physiological (functions), or behavioral
change that improves a population’s ability to
survive.
22. Evolution by Artificial Selection
• Artificial selection is the selective breeding of
organisms, by humans, for specific desirable
characteristics.
• Dogs have been bred for certain characteristics.
• Fruits, grains, and vegetables are also produced
by artificial selection. Humans save seeds from
the largest, and sweetest fruits. By selecting for
these traits, farmers direct the evolution of crop
plants to produce larger, sweeter crops.
23. Evolution by Resistance
• Resistance is the ability of an organism to
tolerate a chemical or disease-causing agent.
• An organism may be resistant to a chemical when
it contains a gene that allows it to break down a
chemical into harmless substances.
• Humans promote the evolution of resistant
populations by trying to control pests and bacteria
with chemicals.
24. Pesticide Resistance
• A pesticide sprayed on corn to kill
grasshoppers, for example, may kill most of
the grasshoppers, but those that survive
happen to have a gene that protects them
from the pesticide. These surviving insects
pass on this resistant gene to their offspring.
• Each time the corn is sprayed, more resistant
grasshoppers enter the population. Eventually
the entire population will be resistant, making
the pesticide useless.
