A large body of molecular evidence supports a variety of mechanisms for large evolutionary changes, including: genome and gene duplication, which facilitates rapid evolution by providing substantial quantities of genetic material under weak or no selective constraints; horizontal gene transfer, the process of transferring genetic material to ...
Atavisms are often seen as evidence of evolution. [6] In social sciences, atavism is the tendency of reversion: for example, people in the modern era reverting to the ways of thinking and acting of a former time. The word atavism is derived from the Latin atavus—a great-great-great-grandfather or, more generally, an ancestor.
Mosaic evolution – Evolution of characters at various rates both within and between species; Parallel evolution – Similar evolution in distinct species; Quantum evolution – Evolution where transitional forms are particularly unstable and do not last long; Recurrent evolution – The repeated evolution of a particular character
Beginning of animal evolution.

[59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...

Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...

7. Salsa Verde. Salsa verde and Doritos are the combo we didn't know we needed. The bright and fresh flavors of jalapeño, onion, and tomato make these much lighter than the standard Dorito offerings.
