With reference to fossils, Colin ...
Sorry,
Roland Pires, but a personal opinion of a single scientist in a letter is not scientific evidence.
If there were any intermediate fossils we should see numerous ones not a few which could be misinterpretations or fakes.
We have maybe millions of "intermediate fossils":
Transitional fossils.
We have found a handful of fakes. Misinterpretations would be more plentiful.
A recent study on mitochondria DNA on animal species found that 9 out of 10 species on Earth today including humans came into existence at the same time about 100,000 to 200,000 years ago
This is an erroneous article that has lead to some lies on the Internet,
Roland Pires.
Sweeping gene survey reveals new facets of evolution misrepresented what the paper stated. The authors stated genetic diversity accumulated over a period of 200,000 years, not that new species evolved.
Homo sapiens are ~315,000 years old, not 200,000.
What did the paper actually demonstrate, and why is it important?
First, Stoeckle and Thaler examined the variation in a 600-nucleotide region of one gene in the genome of the mitochondria for five million individual animals representing 100,000 animal species. They concluded that the genetic diversity of mtDNA is relatively low (about 0.2% differences in the gene they examined, or about a 1 nucleotide difference) within most species. This is true whether that species had a restricted geographical range and/or population size (e.g. African elephants) or if the species had a large population and geographic range (e.g. humans). As we will see, it is this result that has led to the incorrect claim that most species originated about the same time.
Stoeckle and Thaler did not conclude "90% of animal species appeared at same time as humans". They wrote "the genetic diversity observed in mitochondrial genomes of most species alive today can be attributed to the accumulation of mutations from an ancestral genome within the past 200,000 years.".
Another problem for the evolutionary theory is that it depends on invalid extrapolations.
This is not true,
Roland Pires.
Human breeding of animals is not evolution. Human breeding of animals does lead to almost species, e.g. a dog is not a wolf, an Irish wolf hounds tend not to breed with toy dogs .
We have observed a new species of finch emerge. We have observed many new species emerge.

A creationist author's web page is not a reliable source of biology,
Roland Pires.
This is
Lee Spetner. He is a physicist who does not believe in evolution because of religious beliefs. That is Ok but has lead to him persisting with ignorant ideas about evolution. He has not published any papers on evolution since 1970.
The
Talk Origins news group was a science-based group. They cited scientific literature. For example see
29+ Evidences for Macroevolution: The Scientific Case for Common Descent.
The Evolution of Improved Fitness by Edward E. Max goes through some creationist myths and refutes them with science.
