Answer 1

Try some of the links below. The first one is a downloadable PowerPoint show that will bring lots of information right to your computer and save you a lot of work cutting and pasting. Good luck.

Answer 2

Yeah asking this in Biology sounds plenty like the droves of scholars that bypass in there hoping human beings will do their homework for them. it relatively is a transformation in allele frequency that makes the two inhabitants no longer able or disinclined to interbreed. An accumulation of mutations and epigenetic adjustments try this. sure, it relatively is a chemical replace interior the DNA (organic determination with the aid of differing environments, genetic drift) or a transformation in epigenetic markers that adjustments which genes are expressed and the way. bear in mind, generally species interior the comparable genus, and each so often even genera interior the comparable family participants can nevertheless interbreed and bring achievable fertile offspring, yet because of the fact of morphology or habit they are going to generally p.c. to no longer. So diffused a transformation as shade might reason populations to alter into reproductively remoted from one yet another (with the aid of determination) and then, as diffused adjustments interior the genome collect, they replace into no longer able to interbreed. Sorry, the area constraints make those issues slightly perfunctory. in case you like extra information, you could e mail me.

Go to a local college library and check out " Evolution " third edition, by Mark Ridley. Or try any good ecology text, as they will have plates illustrating the above.
