(please answer all, not partially. If you do not know theses all, Please let other experts answer)

1. Describe the sequence of events leading to self-replicating cells.

2. Briefly describe the evolution of modern humans, and describe our extinct relatives beginning with Ardipithecus ramidus and ending with Homo Sapiens.

3. Racial differences are differences between subgroups of a common species. How might races change over the next 10,000 to 100,000 years?

Solution

Self replicating cells: Self replication is a process in whics cells construct or replicate into an identical copy of itself.

e.g : Biological cells.

Biological cells reproduce by cell division.

Any self replicating mechanism does not make a perfect copy of it self because of the experience of genetic variation.and can create varients of itself.These can be submitted to natural selection.in self replication some of these steps may include ,,, such as.. A coded representation of replicator, mechanism to copy the code, construction with in the environment of the replicator.

machine replicators may follow the events like...replication control-replication information - replication substrate - replicator structure - passive parts - active parts - replication energetics - replication process - replicator performance - product structure - evolvability .

self replicatini cells leads to replication to give rise to their identical copies...
