- Earth formed approximately 4.6 billion years ago with a harsh atmosphere of high heat, water vapor, volcanic activity, and no breathable oxygen.
- Early theories on the origin of life included that it began extraterrestrially or through creationism, but the prevailing theory of chemical evolution suggests that organic compounds formed on the early Earth and combined to produce life.
- The Miller-Urey experiment demonstrated that organic compounds like amino acids and nucleotides can form when basic gases like methane and ammonia are exposed to electric sparks simulating lightning, supporting chemical evolution as a viable theory for how life began.
I tried to integrate basic and important concepts of evolution from different ppt that can be downloaded here in slideshare to have a consolidated theme about evolution.
human evolution, origin of life, big bang theory, theories on origin of life, evolution of life forms, experimental evidence on theory of chemical evolution, evidences of evolution, homology and analogy, biochemical and biogeographical evidences, adaptive radiation, lamarck's theory of evolution, darwins theory of evolution, mechanism of evolution, hardy weinberg principle, mutations
Delivered this as talk series on Evolution to some of my colleagues interested in systems thinking. It was a great learning for me and will incorporate it into a sequel later.

In line with generally accepted theories of evolution, Dinosaur extinction is currently believed to be due to climate change due to various causes. However this is not correct, being inconsistent with known facts. There are only two possibilities. Either Dinosaurs evolved to their extinction or evolved to some other phyletic lines or species with which ancestor – descendent relationship can’t be presently demonstrated.
Author: Dr Mahesh C. Jain is a practicing medical doctor and has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. This is the only book which deals with origin of nature and universe from null or Zero or nothing. Chapter 30 of the book is about Evolution of Life wherein author has worked out a new theory about evolution of life.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
