Agriculture fundamentally changed the way humans live — but at a cost, using up huge tracts of land and wreaking havoc on the environment, even as millions still go hungry. Entrepreneur and investor David Friedberg paints a picture of...

SciShow shares the latest developments in science, this week including new insights into the evolution of giant sperm, and the discovery of a whole new order of animal. ----------

In 2021, workers at a Sardinian aquarium were stunned by the birth of a smooth-hound shark. What was shocking was that, for the last decade, the shark's mother had been living only with other females. So, how was this birth possible? And...

Mosquitoes transmit a number of terrible diseases like malaria, West Nile virus, and the Zika virus, but why not the flu?

SciShow shares the latest developments in science, this week including new insights into the evolution of giant sperm, and the discovery of a whole new order of animal.

In this video Paul Andersen explains the difference between diploid and haploid cells. He starts with a brief description of the central dogma and how genes code for proteins. He then uses the phenotype of red hair to explain that...

Hybrid animals are infertile because of the way their sex cells form. But sometimes, life finds a way.



FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some...

Hank tells us about another great mind in science - Barbara McClintock won the Nobel Prize in Physiology for her discovery of mobile genetic elements and remains the only woman to receive an unshared prize in that category.

On a reef in the Pacific Ocean, 17,000 camouflage groupers dart about in the cloudy water. It is, in fact, an underwater orgy— turned feeding frenzy. An orgy might seem like a rather flamboyant way to breed, but sex in the sea is a...

At SciShow, we ask the tough questions. Today we explore the answer to the question "if identical twin brothers married identical twin sisters, would their offspring be identical?"

Explore chromosomes and karyotypes with the Amoeba Sisters! This video explains chromosome structure, how chromosomes are counted, why chromosomes are important, and how they can be arranged in a karyotype! This video also tackles a few...

When looking at advertisements and commercials the idea that humor sells or sex sells is an emotional appeal, however sometimes that is not what will sell a product. Sometimes the appeal is in the information that...

Genetic variation produces new characteristics and, over generations, drives the evolution of species. But how do new gene types arise and what are the processes behind evolution? Biology - Adaptation And Evolution - Learning Points....

A video entitled “Cells in Your Body” which discusses the two main types of cells that make up the human body, focusing on how each type is formed.

Brit looks back on our fourth month on Nature League, when we explored the theme of sex and reproduction.

This clip demonstrates, step by step, the process of reproduction in ferns.

Plant Reproduction Set: 7, This clip explains how reproduction occurs in ferns as the alternation of generations

Plant Reproduction Set: 8. This clip explains how plants exist in two alternating forms: diploid sporophyte generation and a haploid gametophyte generation.

This clip demonstrates, step by step, the process of reproduction in mosses.

In this video we learn about the distinct differences of egg and sperm cells, which are also known as gametes. We will see how the chromosomes from each cells come together to form our unique genetic code. The gametes (sperm and egg...
