He would probably say that changing conditions led to extinction - but I don't think availability of prey would be one of them.

Anyway, what happened to the simplest form of evolution? ADAPTATION?

Did all food source -prey - suddenly disappeared that there's no time to adapt?

If availability of prey is a problem, you'd think they'd at least learn to live on other things? Develop gills and start doing some dive-fishing? How about eating plants?

Becoming vegetarians?

Isn't evolution supposed to be for survival? My cat prefers to be a vegetarian - and there's not even any meat shortage in her diet! If my cat can eat veggies, why didn't the large predators of the past learned and adapted, considering it was a matter of life and death situation?

If your cat ate only vegetables (supplemented by only a small amount of meat) she would get sick and die. That's a fact.

You don't see adaptation in a matter of a couple of generations, Betsy. It can take years with insects, centuries with mammals. Drastic changes with higher lifeforms might need thousands of years.

Your cat may like to eat veggies but there's no way it can live on a veggie only diet. I had nearly 20 years with my last cat. Let us know how many years YOUR cat lives living exclusively on veggies! You strike me as rather cruel, killing your pet for a silly point.

Mammoths and sabertooths (saberteeth?) simply didn't have enough time to adapt. Climate change apparently happened too quickly. If we have found so many frozen mammoth carcasses in the Arctic it's doubtful if they had even a couple of generations at most.

Trying to use a lack of adaptation when you are dealing with such a short timeframe is either simple scientific ignorance or a deliberate distortion of the facts.

Those species that don't have time to adapt to changing conditions simply die out! That's why they aren't around anymore.

Don't forget that the change in environment and diet can lead to fertility issues, leading to less offspring. Each successive generation gets smaller and smaller, while each animal lives a shorter life.

So species are created for certain environment and can't adapt to different, more milder one.

If that was so gradual, why were mammoths found frozen with still undigested vegetation in their stomachs?
