Discuss how the gradualist model of evolution differs from the punctuated equilibrium model of evolution

Gradualism is something as the name suggests a process that happens with time. So the it is the process through which one species turns in to other or a new species whereas punctuated equilibrium is the model of evolution which is more abrupt and more sudden. The changes within the species happen more when unexpected in the punctuated process.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
