Rabbi Slifkin is a controversial rabbi. The Rabbis are proving now that the world is only about 6000 years old and how the carbon dating is not what the scientists try to prove about the age of the universe. There are now scientists who concur with the Torah and prove how what seems millions/billions of years is really fairly new. His interpretation of 'evolution' goes against what our Rabbis teach, but, otherwise, this video is very informative and interesting in regard to the animal kingdom from the Land of Israel.
