Was the contagion in the first season some sort of first mutation? Why are Walkers able manipulate their environment when later seasons they seem incapable or atleast uninterested?

The first girl we see picking up the Teddy Bear ?! Fence climbing, rock throwing, doorknob turning walkers‽

Im sure im super late to this discussion. I just started watching the show a few weeks ago and got to a point where a character “returned” who I didnt recognize so I started back from the beginning and was thrown off by Teddy Bear girls abilities.
