But why arent we seeing it? Shouldnt something have happened to us since the roman empire?
This was my aunties argument, im just bringing in other points of views to have a look at, to explore other questions!!!
Ive learnt what you said in Biology, and i am not disputing the evidence. My aunties argum,ent was, why aftyer this long have we "stopped"- and i know your propbably thinking that evolution occurs after long periods of time- but how long, and why so long??
Humans have technology which pretty much allows us to work past natural selection, at least far better than any previous species.
In the wild animals which are weak are unable to survive and so their genes are slowly removed from the gene pool; but with humans that doesn't happen, we have medication and technology to ensure a great number of people survive, so the gene pool isn't being filtered out. Get what I mean? Although that's not entirely true as natural selection does still have an effect, which can be seen by looking at changing allele frequencies.
If you're talking about obvious physical changes, well, how many 2000 year old Romans have you seen to compare?
