The most logical answer that I can think from Darwin's Theory of Evolution is that that species had been isolated from other possible panthers to mate with. So after generations of that isolated group of panthers their offspring would eventually become increasingly similar.
Homeostasis: A state of balance reached through reactions within a cell or organism.
Metabolism: The total of all chemical reactions within an organism.
Organism: Any living thing that takes in food, grows, and reproduces.
A salt or ester of phosphoric acid, containing PO43− or a related anion or a group such as —OPO(OH)2.
The right matches are:
• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).
• Involves scraps of genetic material ==> Transformation.
• Uses a virus to transmit genetic material ==> Transduction.
• Uses a pilus to transmit genetic information ==> Conjugation.
• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).
In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.
There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.
Since an animal only becomes more complex, and not simpler, an ancestor to all organisms would have to be the most simple and primitive organism.
