Biology

USPshnik [31]3 years ago

I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.

Do you think humans will be able to genetically engineer future humans in your life time?
Vlad1618 [11]

✯Hello✯

↪  In our life time, I dont think so

↪  They will be making some robots but I think before any of this happens they will have to find a way to modify genes

↪  By modifying genes this could change people's hair and eye colour build etc

↪  This hasnt had any progress, but is sure to come in the future but I dont think unless there is a scientific revolution that humans will be engineered this way in our life span
