Evolutionary Biology

Evolutionary Biology is a subfield in biology that is concerned with the gradual change in the traits of living organisms over generations, especially the emergence of new species. It studies the sequence of events involved in the evolutionary development of a species or of a taxonomic group of organisms.

MIT's ocean model precisely mimics microbes' life cycles
Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs

Robust time estimation reconciles views of the antiquity of placental mammals
Despite great progress over the past decade, the evolutionary history of placental mammals remains controversial.

Sea snails break the law
Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated.

Neutral evolution has helped shape our genome
Researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists.

Evolutionary Pathway To Separate-Sex Plants
When it comes to sex, most plants have the best of both worlds: their sex organs (flowers) are both male and female at the same time.

Selection for the miniaturization of highly expressed genes
What controls the sizes of genes and their introns? Some people believe that genes with complex expression pattern have coding for longer proteins, and contain more undiscovered regulatory motif in their introns (thus they should have longer introns). And
