Curious Kids: how do scientists know evolution is real?

Jenny GravesLa Trobe University

In science, we look at the evidence and try to find the theory that best explains it. And that's what happened when it came to figuring out evolution.

Evolution doesn’t proceed in a straight line – so why draw it that way?

Quentin WheelerState University of New York College of Environmental Science and ForestryAntonio G. ValdecasasCSIC - Consejo Superior de Investigaciones Científicas, and Cristina CánovasCSIC - Consejo Superior de Investigaciones Científicas

If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that's not right at all.

Turtle embryos can choose their own sex, shows new research – but why?

Why humans (or something very similar) may have been destined to walk the Earth

James S. HortonUniversity of Bath and Tiffany TaylorUniversity of Bath

Modern science clashes with the idea that the rise of Homo Sapiens was a fluke.

It’s time we stopped human evolution – geneticist

Alasdair MackenzieUniversity of Aberdeen

One reason for the likes of the anti-vaxxers movement is a misplaced faith in Mother Nature.

Sexual selection in action: Birds that attract multiple mates change their songs more quickly

Nicole CreanzaVanderbilt University and Kate SnyderVanderbilt University

Biologists investigated whether birds that search for multiple mates would evolve ever more elaborate songs to attract them. What they found might have surprised Darwin.

How hunting for crabs in a museum helped unlock secrets of their evolution

Sara MynottUniversity of Exeter

Citizen science game offered clues to why shore crabs get greener as they grow.

These ‘useless’ quirks of evolution are actually evidence for the theory

Ben GarrodAnglia Ruskin University

Why are humans the only animals with chins?

Human evolution is still happening – possibly faster than ever

Laurence D. HurstUniversity of Bath

Natural selection isn't the only factor deciding human evolution.

Charles Darwin’s theory of evolution owes more to his garden than the Galápagos

Ben GarrodAnglia Ruskin University

Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.

Following Alfred Russel Wallace’s footsteps to Borneo, where he penned his seminal evolution paper

Giacomo BernardiUniversity of California, Santa Cruz

An evolutionary biologist visits the remote jungle mountaintop where a little-known naturalist wrote his insightful paper about the mechanisms of evolution that spurred on a rivalrous Charles Darwin.

Natural selection in action: Hurricanes Irma and Maria affected island lizards

Colin DonihueHarvard University

In the wake of two hurricanes in the Turks and Caicos Islands, researchers document for the first time that catastrophic storms can be agents of natural selection, influencing how species evolve.

Guide to the classics: Darwin’s On the Origin of Species

Julia KindtUniversity of Sydney and Tanya LattyUniversity of Sydney

In this age of the pseudo-factual, its more important than ever to acquaint ourselves with the foundations of the scientific tradition, such as Darwin's Origin of Species.

Mother’s milk holds the key to unlocking an evolutionary mystery from the last ice age

Leslea HluskoUniversity of California, Berkeley

Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.

Are humans still evolving? Freediving people have evolved to stay underwater longer

Jan HooleKeele University

New research shows the Bajau Laut people of Southeast Asia have evolved bigger spleens to store more oxygen-rich blood.

Discovery of a surprise multitasking gene helps explain how new functions and features evolve

Katherine L. PetrieUniversity of California San Diego and Justin MeyerUniversity of California San Diego

A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
