Conditional.
I am an ESOL student. My language is Spanish. I cannot decide which sentence is correct:
If animals like horses, cows, and bulls had not helped people at work, humankind would not have exhibited the development that it has today.
or
If animals like horses, cows, and bulls had not helped people at work, humankind would not exhibit the development that it has today.
Thanks

"If animals, such as bulls, cows, and horses, were not domesticated and put to work, humankind would not have reached the level of development seen today."
