Thanks but the Fossil Record is not scientific method science, it's purely speculative because its not observable, repeatable, or refutable and thus does not qualify as either a scientific fact or theory. Sounds like a faith to me?
A major evolutionary innovation has unfurled right in front of researchers' eyes. It's the first time evolution has been caught in the act of making such a rare and complex new trait.
And because the species in question is a bacterium, scientists have been able to replay history to show how this evolutionary novelty grew from the accumulation of unpredictable, chance events.
Twenty years ago, evolutionary biologist Richard Lenski of Michigan State University in East Lansing, US, took a single Escherichia coli bacterium and used its descendants to found 12 laboratory populations.
The 12 have been growing ever since, gradually accumulating mutations and evolving for more than 44,000 generations, while Lenski watches what happens.
Mostly, the patterns Lenski saw were similar in each separate population. All 12 evolved larger cells, for example, as well as faster growth rates on the glucose they were fed, and lower peak population densities.
But sometime around the 31,500th generation, something dramatic happened in just one of the populations - the bacteria suddenly acquired the ability to metabolise citrate, a second nutrient in their culture medium that E. coli normally cannot use.
A team led by bioengineering researchers at UC San Diego report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. Scientists have previously published static "snapshots" of the genome sequences of more than 100 bacterial species, from the harmless to those that cause plague, but this new report shows how these genomes are moving targets.

They are different species of the same Kind = same genus.
Noun: The formation of new and distinct species in the course of evolution
"The mechanism of sympatric speciation has been experimentally verified for many plants. One example is a group of species, collectively called hemp nettles, that occurs in temperate parts of Europe and Asia. One hemp nettle, Galeopsis tetrahit (2n = 32), is a naturally occurring allopolyploid thought to have formed by the hybridization of two species, G. pubescens (2n = 16) and G. speciosa (2n = 16). This process occurred in nature but was experimentally reproduced. Galeopsis pubescens and G. speciosa were crossed to produce F1 hybrids, most of which were sterile. Nevertheless, both F2 and F3 generations were produced. The F3 generation included a polyploid plant with 2n = 32 that self-fertilized to yield fertile F4 offspring that could not mate with either of the parental species. These allopolyploid plants had the same appearance and chromosome number as the naturally occurring G. tetrahit. When the experimentally produced plants were crossed with the naturally occurring G. tetrahit, a fertile F1 generation was formed. Thus, the experiment duplicated the speciation process that occurred in nature."

As hard to believe as evolution is, its only made impossible by the fact that a male and female evolve at the same time, and that their respective sperm and egg are in synch.
Only those with a faith far outstripping that of a creationist, could accept that happened.
thats simply not true
mutations are passed down from one parent to the baby not both. if you look at how chromosomes work youll understand.

I think it's a valid question.
It's funny that no one has an answer, only insults.
Grow up children of science.
You are lead by blind faith.
Just as much as Christians.
