Answer:
Life is suggested to have started in an aquatic ecosystem - the ocean.
Explanation:
For decades, life has been suggested to have started in an aquatic environment due to evidence of ancient fossils and chemical studies.
Recently, scientists have been able to narrow these suggestions to state that life originated in a deep sea hydrothermal vent. This hypothesis arised due to the presence of chemicals that are thought to have produced the chemical reactions that are necessary for the evolution of life.
The first living forms on Earth were single-celled micro-organisms called stromatolites - <em>rock-like structures formed by cyanobacteria</em> - that appeared around four billion years ago. Interestingly, we are still able to find these ancient creatures but only in specific regions of the world such as Cuatro Cienegas, Coahuila in Mexico.
A. Become cancer because in the process of mitosis (cell replication) idlf the cell replication does not work properly and keep going on and on it will begin creating mutations to help it replicate causing cancer to happen.
Ex: let's say you have a paper cut. Your blood cells must replicate in order to close that gap in your body. They begin replication but if they get out of control and begin creating mutations it will turn into cancer.
Genetic drift can lead to speciation as it allows variation within the genes of a species. For instance, genetics can soon evolve into a new phenotype in a species - humans with tails, cats with gills, etc.
Therefore, genetic drift can lead to speciation as it allows variety and evolution to occur within the genetics of a species.
Hope this helps!
