Answer:
Agricultural revolution, start of Neolithic era, maybe 12000 yrs ago
Explanation:
Answer:
1. Leads to mixing of genetic materials hence variation within species
2. Leads to offspring with hybrid viguor that tend to show high and adaptability to environmental conditions.
3. Variations due to sexual reproduction leads to improvement of species hence evolutionary changes that may bring about specialisation
Answer:
formed of ice, rock, and dust
develop tails near the Sun
Explanation:
Comet is a smaller celestial body which is mainly composed of ice and dust.
The other components of this comet are rocks and gas.
When any comet approaches a sun it can deliver a tail of dust or gas.

<span>The answer is A. Variation in gene pool
Speciation is a formation of a new species during the evolution line.
When there is a variation in a gene pool, a unique combination between genes could be formed during the mating process. This will create an offspring with unique gene pool that will lead to speciation</span>
Skeletal muscle just attach to the skeleton of the body by itself.
