CULTURAL QA 01202421 Q2 Is it believed that all living things on Earth have evolved from a single common ancestor through natural selection?
KR LUCA stands for "Last Universal Common Ancestor." LUCA is a theoretical concept in evolutionary biology that represents the most recent common ancestor of all life on Earth. According to the theory of common descent, all living organisms share a common ancestry, and LUCA is considered the hypothetical organism from which all life forms evolved. LUCA is not an individual organism that existed in a specific time and place; rather, it is a concept used to represent the point in evolutionary history where the lineages leading to all extant life forms converged. LUCA is thought to have lived billions of years ago, likely before the divergence of the three primary domains of life: Bacteria, Archaea, and Eukaryota. While LUCA is a widely accepted concept in the field of evolutionary biology, it is important to note that it is based on inference and is not directly observable. The study of LUCA involves examining genetic and biochemical evidence to infer common ancestry among different life forms. So half baked knowledge is always dangerous. I shall write about Darwin and Luca sometime later. Incidentally born in India , why would not one apply their mind as we have a huge treasure? Q4 Were any Shankaracharyas present at the Bhoomi Pujan ceremony in Ayodhya? If so, what was their opinion on the issue? KR Half baked knowledge is dangerous; Kanchi yes; Sringeri is going as he has to take a retinue and invitation is confined to a small number which Raja Matam cannot follow as per protocol. Except Puri all had certain representations including heavy donations. Q5 story appears to be like the film Pichaikkaran?
