Bats and birds are unrelated animals, yet they both evolved wings. by acquiring similar traits (i.e., wings) as they adapted to similar environments, these species exhibit convergent evolution through analogy present between the wings. Convergent evolution happens when two distantly related organisms acquire the similar traits in response to the similar habitat or niche.  

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
