    1. Organisms that exhibit Type I survivorship curves have the highest probability of surviving every age interval until old age

      So I know that some species of shark or other life can survive for hundreds of years. This may be a little off topic but how can they do this and would this not affect the curve of this drastically for the animals that do survive for possible centuries

    1. predation

      I heard that because humans over hunted some wolfs that it eventually lead to a river changing its path. Here is the situation I am talking about from google: "human hunting of wolves led to a trophic cascade where the absence of wolves in places like Yellowstone National Park allowed elk populations to boom, overgrazing riverbanks, leading to increased erosion and degraded river systems" Has there been more than one occasion somthing like this has happened and if so has this been studied extensively?

    1. photosynthesis

      Using genetic modification like CRISPR-Cas9 would it be possible to make any animal capable of photosynthesis? Possibly humans as well and would this have any significant changes to said species like green skin?

    1. There are 118 elements, but only 92 occur naturally. The remaining elements are synthesized in laboratories and are unstable.

      I watched a video on discovering non naturally occurring elements and how difficult it was to find new elements to the half life of said elements being so short. Using AI or other automation would it be possible to measure these short half life elements due to the increased speed of processing power? or is it still a requirement that the element has to exist for a set amount of time?
