Our only reason for supposing the evolution of life, made plain by fossil records, to have taken place very slowly is that geologists have stated that the deposition of the strata took place very slowly.
This fossil record has given us our best knowledge of the course by which the present living world has been brought into its existing condition.
Biases in the fossil record can be due to features or mechanisms predating or postdating the collecting or during the collection process itself.
Nobody is pretending from this latter perspective that the fossil record is perfect, but it is argued it is good enough to derive a history.
However, despite the abundance of sequence data from genomes of organisms, molecular time estimates rely on accurate calibrations, usually from the fossil record.
This is unlikely to be available, as there is not likely a fossil record of pain faces.
But there are other data from the fossil record, which are surely relevant to the evolution of a less narrowly defined object of study.
The fossil record also reveals that anatomical changes that broadened and shortened the pelvis and reshaped the birth canal began occurring well before this exodus.
Managing Your Emotions
What makes me angry?
Vad gör mig arg?
Mostly，l hate when someone tries to make someone else feel bad.
För det mesta hatar jag när någon försöker få någon annan att må dåligt.
I have to admit that once, when l was actually called names.
Jag måste erkänna att en gång, när jag faktiskt kallades öknamn.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
Jag ångrade detta efteråt, men inte helhjärtat eftersom jag tror att jag blev provocerad i denna situation.
The most postive way of dealing with anger is talking about the problem.
Det mest positiva sättet att hantera ilska är att prata om problemet.
l talk to someone who listens, or l'll write my thoughts down on paper.
Jag pratar med någon som lyssnar, annars skriver jag ner mina tankar på papper.
Learning how to deal with anger as you're growing up is so important.
Att lära sig att hantera ilska när du växer upp är så viktigt.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
När du är yngre kan du skrika eller gråta när du är arg, men när du blir äldre blir du förväntas hantera dina känslor mycket bättre.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
Att lära sig att kontrollera dina känslor nu kommer att hindra dig från att göra något som du kommer att ångrar sig senare i livet!
