Debate: 15 questions for evolutionists (view source)
Revision as of 00:00, June 10, 2012

::Similarly, when a large segment of a chromosome is duplicated, every new duplicate gene contained in that segment is entered into the "new gene lottery", for a chance to become new (repurposed) genetic information. This too is a fairly common occurrence, especially when there is a lot of selective pressure for novel adaptation.

::Evolution has been a '''long''' road. It's taken 4 billion years for gene duplication, sequence divergence, random catastrophes, population events, and the cut-throat race for reproductive viability to lead to life as we know it today.

::::[[Hardy Weinberg equilibrium]] is a model for what the genes of a living thing would be if they did not evolve. In this model, forces that change genetic frequency, such as mutations, genetic recombination, and so on, would have no effect. This concretely means that if a population has Hardy Weinberg equilibrium, and if, say, fifty percent of the individuals having one allele (alleles are versions of a gene) and fifty percent has another, then over, say, a thousand generations, fifty percent would still have one allele and fifty percent the other.
