Divergent:  is the combination of different traits and characteristics from groups which can lead to the formation of new species. This is when different species mate and combine their genes.

This extinction was caused by an asteroid impact which caused catastrophic methane release and low oxygen levels. This extinction occurred about 248 million years ago.]]> 2017-06-14 15:54:30 UTC https://padlet.com/mary_nash/en5v349lvbj3/wish/176424927 mary_nash https://padlet.com/mary_nash/en5v349lvbj3/wish/176425578 Towards the end of the Triassic-Jurassic period three phases of extinction led to nearly half of all the species alive at the time to become extinct. The three events that led to this mass extinction were climate change, flood basalt eruptions and an asteroid impact. These events occurred about 200 million years ago.]]> 2017-06-14 15:59:20 UTC https://padlet.com/mary_nash/en5v349lvbj3/wish/176425578 mary_nash https://padlet.com/mary_nash/en5v349lvbj3/wish/176426111 This mass extinction occurred about 65 million years ago and is known for being the end of the dinosaurs. There are many things such as a flood basalt eruptions affecting the world's climate, combined with drastic falls in sea level and a huge asteroid or comet striking the earth that led to this extinction. ]]> 2017-06-14 16:03:42 UTC https://padlet.com/mary_nash/en5v349lvbj3/wish/176426111
