Fossils - GCSE Biology
🦊 In this GCSE Biology video, we explain how fossils are formed through the preservation of organisms in conditions that prevent decay, such as low oxygen, temperature, and moisture. Layers of sediment, like volcanic ash or sand, press down on dead organisms, contributing to fossil formation, while the harder parts of the organism are replaced by minerals as they decay, leaving behind impressions. Various types of fossils, including intact preserved remains, impressions, and trace fossils like footprints or rootlet traces, provide valuable insights into Earth's past biodiversity.

Evidence for Evolution - GCSE Biology
Переглядів 362 години тому
🦊 In this GCSE Biology video, we discuss additional evidence supporting the theory of evolution beyond fossils, including advancements in understanding genetics and the observation of antibiotic resistance in bacteria. By studying the inheritance of characteristics through genes and observing how bacteria evolve to become antibiotic resistant, scientists have further validated the theory of evo...
Gene Theory - GCSE Biology
Переглядів 324 години тому
🦊 In this GCSE Biology video, we introduce gene theory, which posits that characteristics are passed on to offspring through units called genes found on chromosomes. This theory developed in the late 19th and early 20th centuries, building upon the observations of Mendel and advancements in understanding chromosome behavior and DNA structure. Through the work of various scientists, including Wa...
Gregor Mendel - GCSE Biology
Переглядів 317 годин тому
🦊 In this GCSE Biology video, we introduce Gregor Mendel, an Austrian monk who conducted groundbreaking experiments with pea plants in the mid-19th century. Despite Mendel's meticulous observations and discoveries about inheritance patterns, his work went unrecognized during his lifetime due to the lack of understanding of genetics and the obscurity of his publications. However, after his death...
Speciation - GCSE Biology
Переглядів 529 годин тому
🦊 In this GCSE Biology video, we explain speciation as the gradual formation of new species through the process of evolution, initially proposed by Alfred Russel Wallace during his travels in Asia. Speciation occurs as individuals of a single species become isolated due to changing environmental conditions, leading to genetic variation and the selection of traits better adapted to the new envir...
Jean-Baptiste Lamarck - GCSE Biology
Переглядів 4312 годин тому
🦊 In this GCSE Biology video, we introduce Jean Baptiste Lamarck, a French biologist whose ideas influenced Darwin's theory of evolution. Lamarck proposed that animals adapted to their environment through the use and disuse of certain features, believing that acquired characteristics could be passed on to offspring. However, subsequent research and evidence, including the discovery of genetic i...
Theory of Evolution Controversy - GCSE Biology
Переглядів 6314 годин тому
🦊 In this GCSE Biology video, we explain the publication of Darwin's "On the Origin of Species" in 1859, which introduced the theory of evolution by natural selection. Despite its popularity, the book stirred controversy due to its challenge to the prevailing religious belief of creationism and the lack of sufficient evidence and understanding of genetic mechanisms at the time. This led to skep...
The Theory of Evolution by Natural Selection - GCSE Biology
Переглядів 4816 годин тому
🦊 In this GCSE Biology video, we discuss the theory of natural selection, which was independently proposed by both Darwin and Wallace. While Darwin is often credited as the father of evolution, Wallace played a significant role in its development. Their joint writings and collaboration led to the publication of "On the Origin of Species" by Darwin in 1859, a seminal work that established the co...
Alfred Russel Wallace - GCSE Biology
Переглядів 5419 годин тому
🦊 In this GCSE Biology video, we highlight Alfred Russell Wallace's contributions to evolutionary theory, showcasing his independent proposal of the theory of evolution by natural selection. Alongside his work on warning coloration in animals, Wallace pioneered theories of speciation, elucidating the process by which new species form. Despite the slight differences in their beak shapes, Wallace...
Charles Darwin - GCSE Biology
Переглядів 4921 годину тому
🦊 In this GCSE Biology video, we introduce Charles Darwin and his groundbreaking contributions to science, particularly his theory of evolution by natural selection. Darwin's extensive observations during his voyage on the HMS Beagle led him to propose this theory, which revolutionized biology by explaining how all life on Earth developed from simple organisms. Despite controversy, Darwin's ide...
Benefits and Risks of Cloning - GCSE Biology
Переглядів 51День тому
🦊 In this GCSE Biology video, we discuss the benefits and risks of cloning, particularly in agriculture and medicine. While cloning offers advantages like rapid production of offspring with known traits and preservation of endangered species, it also poses risks such as reducing genetic diversity, increasing susceptibility to diseases, and potentially yielding less healthy clones compared to th...
Adult Cell Cloning - GCSE Biology
Переглядів 62День тому
🦊 In this GCSE Biology video, we explain adult cell cloning, a technique where the nucleus of an unfertilized egg cell is replaced with the nucleus from an adult body cell. This process, famously exemplified by Dolly the sheep in 1996, results in the creation of an embryo containing genetic information identical to the donor body cell. After stimulating the egg cell to divide and form an embryo...
Embryo Transplants - GCSE Biology
Переглядів 51День тому
🦊 In this GCSE Biology video, we explain embryo cloning, a method used to create multiple identical offspring from animals with desirable traits. Initially, sperm from a bull is artificially inseminated into a cow, resulting in the development of multiple embryos. These embryos are then removed from the cow's uterus, split into more embryos, and finally transplanted into host mothers, leading t...
Tissue Culture - GCSE Biology
Переглядів 53День тому
🦊 In this GCSE Biology video, we introduce tissue culture as a method to propagate identical new plants from small groups of cells taken from a parent plant. After placing the tissue sample in a Petri dish with agar jelly and nutrients, tiny plantlets develop, which are then transferred to compost to grow into mature plants. Tissue culture is particularly valuable for preserving rare plant spec...

Hi
Thank you for your services. It was highly appreciated❤Gcses finished!!
i love you
First view and comment
Wtf
Very interesting

boooooooooo :(
U
shutthehellup man
Iloveyou
bruh, i am giving this a dislike
This was brilliant mate thanns
Please help me differentiate between Autonomic and somatic
What u doing u are wrong second name in classification is lower case!!! Poor from u
to all the students who are watching this to learn how to name benzene ring with multiple sub do not watch this video it does not explain it right.
Most useless video ever
Watching this exactly 12 hours before paper 3 hoping I’m saved 😭
Thank you
