|
|
Through artificial selection, larger horses survived and were chosen to reproduce offspring.
|
|
|
Through artificial selection, small horses were bred out of the gene pool, leaving only larger horses.
|
|
|
Through natural selection, favorable adaptations were passed to offspring, allowing for the evolution of the horse.
|
|
|
Through natural selection, horses acquired traits that produced changes and then were passed on to their offspring.
|
Detailed explanation-1: -Through natural selection, horses acquired traits that produced changes and then were passed on to their offspring.
Detailed explanation-2: -Which best accounts for the changes in the horse? Through natural selection, favorable adaptations were passed to offspring, allowing for the evolution of the horse.
Detailed explanation-3: -The development of larger limbs and hooves allowed horses to spread out and become more successful in grassland habitats as they developed. At the same time, the fossils show that horses developed teeth which are more suited to their changing diet-grazing grasses rather than browsing.
Detailed explanation-4: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’
Detailed explanation-5: -Summary: New research that analyzed more than 270 million years of data on animals shows that mammals and birds–both warm-blooded animals–may have a better chance of evolving and adapting to the Earth’s rapidly changing climate than their cold-blooded peers, reptiles and amphibians.
