Galileo Galilei (Unit 2. The cell 🦠)
He adapted lenses from the telescope and also invented a compound microscope -
Robert Hooke (Unit 2. The cell 🦠)
He proposed the term cell after looking at a thin layer of cork under a microscope. -
Anton van Leeuwenhoek (Unit 2. The cell 🦠)
He built a simple microscope with a single lens, he discovered microscopic living things and he called them animalcules or small animals. -
Alexander von Humboldt (Unit 5. Ecosystems 🌾)
In his work Essay on the Geography of Plants, he anticipated the concept of the ecosystem by recognizing the interaction between climate, soil, plants, and animals. -
Mary Anning (Unit 6. Evolution 🔁🧬)
She discovered marine fossils such as the ichthyosaur and plesiosaur on the cliffs of Lyme Regis, England. Her findings in the 1820s began to challenge the idea that all species had always existed, supporting future theories of evolution. -
Matthias Schleiden (Unit 2. The cell 🦠)
He developed the cell theory. -
Theodore Schwann (Unit 2. The cell 🦠)
He developed the cell theory. -
Rudolf Virchow (Unit 2. The cell 🦠)
He add another statement in the cell theory when he proved that cells reproduce. -
Alfred Russel Wallace (Unit 6. Evolution 🔁🧬)
In 1858, he sent a letter to Darwin outlining his own theory of evolution by natural selection. He reached the same core idea independently, leading to the joint publication of their theories. -
Charles Darwin (Unit 6. Evolution 🔁🧬)
He published On the Origin of Species in 1859, where he developed the theory of natural selection. His work became the starting point of modern evolutionary biology. -
Gregor Mendel (Unit 4. Mendelian Inheritance 🌱 )
Austrian monk who described the basic laws of inheritance through experiments with pea plants. -
Thomas Hunt Morgan (Unit 4. Mendelian Inheritance 🌱 )
He worked with fruit flies and discovered the genes linked to chromosomes. -
Florence Sabin (Unit 2. The cell 🦠)
First woman to be part of the National Academy of Sciences of the USA, studied the development of lymphatic system cells and researched white blood cells and the immune system. -
Oswald Avery (Unit 4. Mendelian Inheritance 🌱 )
It showed that DNA is the hereditary material (experiments with bacteria) -
Barbara McClintock (Unit 2. The cell 🦠)
He showed how genes can be controlled at the cellular level. -
Aldo Leopold (Unit 5. Ecosystems 🌾)
He was an American ecologist and environmental philosopher who developed the "land ethic" — a philosophy promoting a respectful and responsible relationship between humans and nature. -
Martha Chase (Unit 4. Mendelian Inheritance 🌱 )
He showed that DNA is the genetic material -
Maurice Wilkins (Unit 3. Genetic information 🧬)
He discovered the structure of the DNA molecule. -
James Watson (Unit 3. Genetic information 🧬)
He discovered the structure of the DNA molecule. -
Francis Crick (Unit 3. Genetic information 🧬)
He discovered the structure of the DNA molecule. -
Rosalind Franklin (Unit 3. Genetic information 🧬)
He discovered the structure of the DNA molecule. -
Eugene Odum (Unit 5. Ecosystems 🌾)
He was an American ecologist who defined the modern concept of the "ecosystem" as a functional unit. -
Jane Goodall (Unit 5. Ecosystems 🌾)
She studied chimpanzee behavior in their natural habitat in Tanzania. -
Rachel Carson (Unit 5. Ecosystems 🌾)
She published the book Silent Spring, in which she exposed the devastating effects of the pesticide DDT on ecosystems. -
Sylvia Earle (Unit 5. Ecosystems 🌾)
She has dedicated her career to studying and protecting marine ecosystems, becoming one of the most important voices in ocean conservation. -
Peter Grant (Unit 6. Evolution 🔁🧬)
He began studying the Galápagos finches with Rosemary Grant in 1977. Their research showed that evolution can happen over short time periods, with measurable changes observed across generations. -
Rosemary Grant (Unit 6. Evolution 🔁🧬)
Together with Peter Grant, she began field studies on the Galápagos finches in 1977. They provided direct evidence of evolution in real time, showing how species can change within just a few generations. -
Elizabeth Blackburn (Unit 2. The cell 🦠)
Her work is key to understanding cellular aging and cancer in other cells. -
Rita Levi-Montalcini (Unit 2. The cell 🦠)
Her work is essential for understanding how nerve cells grow and communicate. -
Margarita Salas (Unit 3. Genetic information 🧬)
She discovered of the DNA polymerase of the bacteriophage virus phi29. -
Jennifer Doudna (Unit 3. Genetic information 🧬)
He designed the CRISPR-Cas9 system, a revolutionary tool for genetic editing.
