You seem to imply that Malaria has killed more humans throughout history than heart disease. Laughably, you do not show any source to back up your statement ¯\_(ツ)_/¯.
I disagree based on extremely easy to obtain numbers from sources like [1]. Malaria at 200k/year is not even close to Ischaemic heart disease at at about 9M/year. That is an almost 50-fold difference (!). Given that we have experienced an exponential growth in population in the last 100 or so years, I would not be inclined to believe that something in the past has enough weight to shift the numbers in such dramatic way to invert this trend (50 to 1); and that's being VERY generous and assuming that somehow, in the past, for whatever reason, nobody died from heart disease, at all.
If you have a substantial contribution to make please do so and provide data to support your arguments, otherwise, refrain from spreading lies and FUD.
ah, I see the confusion. Heart disease may have killed more, cancer too, but neither of those are animals. The stat easily stands at mosquitoes being the number one deadliest animal to humans of all time.
