‘Biologists’ suggested that organisms have been around for a long time and can change too.
What was Larmarck’s conclusions?
Jean-Baptiste Lamarck, an early French biologist, proposed the theory of inheritance of acquired characteristics. Lamarck believed that organisms have an innate drive to become more complex over time and that they can change during their lifetime in response to their environment. He suggested that these acquired traits could then be passed on to future generations. His theory was largely based on observations of giraffes and their long necks.
To find Lamarck's conclusions in more detail, you can read his work "Philosophie Zoologique" which was published in 1809. In this book, Lamarck explains his theory of evolution, provides examples of species changing over time, and makes conclusions about the process of inheritance of acquired characteristics. Additionally, you can also refer to various biology textbooks, research papers, and scholarly articles that discuss Lamarck's contributions to the field of biology and his conclusions regarding inheritance and evolution.
