Scientists observe two distinct group of anole lizards living in the same forest. Genetic analysis revealed that the two groups are very closely related and occasionally produce fertile hybrids. The two groups are nonetheless considered different species. One species is large and occupies the trunk of trees,rand mainly feeds on beetles. The other species is small, occupies the canopy and mainly feeds on flies. What mechanism most likely contributed to speciation in this case? Mechanical isolation Allopatric isolation Gametic isolation O Hybrid unviability OHabitat isolation

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.
