Matthew Liang's independent learning log 3

Learning log 3




What I did: I went to National Geographic when there is an interesting article which caught my eye, especially the phrase, 'tiny vampires', and made me read on and discover.

Words I did not know:

Autopsy- An examination of a dead body to find out the cause of death.

Attest- To affirm to be true or genuine.

What I learnt:

-We may owe our existence to these organisms and their type, for they are responsible for ushering an era whereby life on Earth went from bland to brutal.

-The tiny vampires eat their prey by puncturing their outer skin before eating their innards, piece by piece.

Summary: An autopsy of the fossilised remains attests to gruesome deaths.The single celled organisms were discovered in the Grand Canyon and are covered in little holes. A tell-tale sign of microscopic vampire attacks by predators. What was most significant was the timing of the attacks, which was in an era when life on our planet was undergoing swift, dramatic change.After being stuck in an evolutionary rut for roughly a billion years, new species were finally beginning to appear. Because of this, it is believed that the driving force of this event was the rise of these mini vampires as they unleashed an evolutionary arms race that compelled life to diversify in order to survive the onslaught.Also,  if it is correct, we owe our existence to these mini vampires.
