Would we even call them new species within a few hubdred years or would they be seen as “just variations”?
Many species are absolutely thriving under human invasion and forming new behavioral and breeding patterns that in some cases are even leading to physical changes. Many burds like crows and sparrows love human environments. Trash pandas love us too. Hawks love cities almost as much as mountains. So many tall places to survey from.
There’s also fish who have started being smaller in adult size due to sports fishing and size regulation. Stuff like that.
Oh and crowd are known to have branched into novel food sources because they can use cars to break hard nuts they otherwise couldn’t open.
It’s not all doom and gloom. Nature is hella robust.
- gerbilly 7y agoThis is a well written article on the topic. It argues that human pressures may be selecting out only the hardiest most adaptable species such as rats, mice, pigeons, sparrows, etc... If this goes on unabated, we'll be left with an ecosystem with much lower diversity. http://www.davidquammen.com/sampler/18-planetofweeds http://www.davidquammen.com/sampler/18-planetofweeds
