The 2022 edition of the National Science Board’s report "Science and Engineering Indicators" includes the results of a survey of public knowledge and attitudes about science. 92% of those ...
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [39] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
For example, speciation can be discussed in terms of the ‘mode’, i.e. how speciation occurs. Different modes of speciation include sympatric and allopatric). Additionally, scientists research the 'tempo' of speciation, i.e. the rate at which species change genetically and/or morphologically.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

A paradigm shift is a fundamental change in the basic concepts and experimental practices of a scientific discipline.It is a concept in the philosophy of science that was introduced and brought into the common lexicon by the American physicist and philosopher Thomas Kuhn.
Using your brain to read a book, solve a puzzle, or learn to play an instrument, for example, allows for neurons to make new memories, which creates a feedback loop of maintaining brain health ...
The report said that creating mirror life was a longer-term aspiration of multiple laboratories and major funders of research as part of efforts to better understand life and potentially aid in ...
This change increases the chances of survival and reproduction of the organism (this can be referred to as an organism's fitness). For example, Darwin's Finches [8] on Galapagos island developed different shaped beaks in order to survive for a long time. Adaptive evolution can also be convergent evolution if two distantly related species live ...
