Detailed explanation-1: -These acquired characteristics would also appear in their descendants. Lamarck incorrectly theorized that offspring inherit acquired traits from their parents, but correctly theorized that species evolved from other species.
Detailed explanation-2: -Unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human “perfection.” Species didn’t die out in extinctions, Lamarck claimed. Instead, they changed into other species.
Detailed explanation-3: -In short, Lamarck’s theory was based on two ideas – adaptive change and the inheritance of traits acquired during an individual’s life. This latter idea already formed part of the thinking of other naturalists of his time.
