Experimental evolution

Experimental evolution has been studied in 3 papers since 2016: none in people yet, 2 in animals, 1 in cells; 1 in the past year. The research so far is in animals and cells. The newest story, Oct 30, 2026: “DNA copy differences tied to lifespan in seed beetles”.

What did studies of Experimental evolution find?

Studies of Experimental evolution measured 3 outcomes; the most studied are lifespan (1 study), replicative lifespan (1) and mitochondrial DNA maintenance (1).

Lifespan

upin S. beetle1

1 study

Experimental evolution extends lifespan in S. beetle (compared with populations evolved under regimes favoring a short life) (near doubling of lifespan).
“Replicated populations evolved under regimes favoring either a short or long life, resulting in a near doubling of lifespan.”

Replicative lifespan

upin yeast cells1

1 study

Experimental evolution extends replicative lifespan in cells displaying enhanced mtDNA retention.
“cells displaying enhanced mtDNA retention also exhibit a prolonged replicative lifespan”

Mitochondrial DNA maintenance

upin yeast cells1

1 study

Experimental evolution increases mitochondrial DNA maintenance in evolved lines challenged with mtDNA-damaging reagents.
“the ability to maintain functional mtDNA was enhanced in most of the evolved lines when challenged with mtDNA-damaging reagents”

What is Experimental evolution linked with?

Studies link Experimental evolution with 1 measure, most often reproductive fitness (1 study).

Reproductive fitness

upin worms1

1 study

Experimental evolution is associated with reproductive fitness in worms.
“Differences are observed in reproductive fitness along with related changes in reproductive timing.”

DNA copy differences tied to lifespan in seed beetles

After more than 200 generations, populations selected for long life showed a near doubling of lifespan compared with those selected for short life.After more than 200 generations, populations selected for long life showed a near doubling of lifespan compared with those selected for short life.
