[ QUOTE ]
2 and 3 are wrong, and I think 4 is by extension. Microevolution is simply change in allele frequencies within a population. Alleles are the different versions of a given gene. Macroevolution typically deals with larger scale evolutionary phenomena. An example given on wiki is how feathers appeared from birds when they diverged from one group of dinosaurs. Speciation isn't really a micro/macroevolution question. It occurs on both levels, depending on how you look at it. It is of course related to changes in allele frequencies, as these changes alter the reproductive capabilities of the animals. And it's related to macro as well b/c you're looking beyond a single simple population. I'm not sure I understand #5. What does "GM'd parents" mean? If you're wondering if the offspring are "separate species", the answer is no because they cannot interbreed at all. [/ QUOTE ] Why is two wrong? This is part of why I said "I don't know WHAT people mean when they use the absurd version of the term 'macroevolution.' What makes a "large change" and what represents shifting allelic frequencies? Feathers on birds count but lighter and lighter skin doesn't? Feathers are just the extreme end of the scales scale, pardon the pun. |
