Starting from a single wild canine species, humans have developed hundreds of breeds of domestic dogs. Which of the following statements is supported by this observation? 1) Natural selection had not occurred very frequently in the wild dog populations. 2) There was enough heritable variation in the wild canine species to create a variety of features. 3) Heritable variation is low; otherwise the there would be more wild dog species. 4) Most of the variation in domestic dog species is a result of variation in nutrition and training.

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
