Predicting Evolution
of the
Modern Horse Horse's Evolution The Dew Breed Puddle Island 1400's Dew Breed vs. Modern Horses The Evolutionary Changes to Increase Success 55 Million Years - Present Przewalski's Horse Pony Evolution Pony I Pony II Direct Descendant of the Shetland Pony Forefather of Przewalski's Horse - Mongolia
- Cave images
- Asia + Europe
- Migration, humans lead to instinction
- Last seen in 1969
Dew Breed Modern Horse Size
Teeth
Coat
Hoof
Agility/Speed
Feed environment population predators geography - Cold, wet, rainy
- Windy
- Hills
- Coastal Cliffs
- No trees West Coast of North America
Part of the State of Oregon No naturel predators isolated from humans
Food Sources Abundance of grass + grain 1) Strength 2) Coat 3) Metabolism living in the wild
harsh climate Dark coat absorbs heat Slow metabolism allows for less need for food long mane and tail dark coat to absorb heat thick body thick coat short legs large hooves strong muscles Compare to Quarter Horse and Welsh Pony Mechanisms of Evolutionary Change Mutation- allows for greater variation Random Mating- allows for greater variation Survival of the Fittest- Advantageous traits get passed on to offspring Gene Flow- Climate change forces advantageous adaptions for that climate to be passed on to offspring Environmental Pressures of Other Organisms Ponies are top of the ecological chain on pudddle island Other species= birds, bees, snakes, rabbits, squirrels, frogs, fish No other species is a threat to the horses Predictible?
Testable? 1) 55 Million years
Hyracotherium
2) 52-45 million years
